The registration page has already been setup on the LSAF website. This year, we're going to advertise in AudioXpress magazine. We just signed an agreement with them, and will have 150 free copies of AudioXpress to hand out to attendees. We'll be handing them out at the lobby meeting on Saturday afternoon. How cool is that?

Wayne, this is AWESOME news! I can't wait for this year's show! I know I've been working hard on some new stuff that will be ready by May. I'll also be pitching in a few prizes for this year's LSAF raffle!
Audio Express...cool. I submitted an article to them a few weeks ago. If they are slow, it could show up in that issue. I'm hoping to have a guitar amp to add to our products by then (at least a prototype of it).
I'm hoping to actually make it this year. I've missed the last couple. Bruce, any hints on the guitar amp? I'm looking at picking up a Egnater Tweaker 15 soon, but was also intrigued about building something like an AX84 4-4-0 or SEL as a lower power alternative.
Hi Shane, It's on my bench now in progress. General info is push pull 6L6WXT+ (Sovtek higher capacity version of the 6L6GC) output tubes for about 25 watts class AB1. Could use EL34s, KT77s and others just as well though for nearly the same output. Driver is 12AU7 via a interstage trannie. Input stage is a 12AX7 (SRPP) followed by a tone stack and another 12AX7 for gain. Built on the head amp style chassis (about 7 X 17 inches). It should be ready to test in a month or so. I am putting input / output loop connections for effects but at present don't plan on building them into the basic amp. it should work quite well as either bass or lead.
Sorry to hijack this thread Wayne. Bruce, have you thought about possibly having a switchable tone stack, between bypass, Fender, and Marshall style? With those power tubes you could get a range of sounds that way.
I don't think it's possible to hijack an LSAF thread 'cause it's a place where we showcase our stuff. Pretty much a free-for-all.
Hi, I can do some of that. I want to have it ready for May. A new field for Oddwatt to get into.
I hope you can make it Shane! This year I plan to have a few new things in my room. A new version of the OneSource media server and new revised set of the line array speakers made out of solid walnut! I might even have a few extra things like a new set of bookshelf speakers too...
My LSAF 2013 project is ready for wiring, testing, tuning and painting. It's an open back 8" Dayton Audio PS220-8 Point Source Full-Range Neo Driver with a 15" H-frame eminence Alpha 15 subwoofer, bi-amplified, using a DEQX as the active crossover and equalizer.

Home Theater Shack ran an article on LSAF: Home Theater Shack write-up of LSAF 2013
We will be there. We have a conference room downstairs again. And we might have something very interesting.
I think we'll have something very interesting too: Our new H290C waveguides installed in four π loudspeakers: four π loudspeaker The H290C is the newest waveguide on the market, and has exceptional pedigree owing to its pure oblate spheroidal flare profile. It provides both excellent pattern control and superior acoustic loading. Most horn/waveguides optimize one of the other, but not both. So this is an exciting new device, and has proven itself to deliver excellent performance, both from measurement and critical listening evaluations from hundreds of happy owners who pre-ordered in 2012 and took delivery over the past few months.
Hi All, Oddwatt Audio will be there. We will have the new Dual Mono Poddwatt, The KT120 Mono Blocks (from the assembled kits - not the demos), prototype fully integrated and remote control Stereo KT88 amp, and with luck (if there is no smoke in the beta testing) an all valve guitar amp. A wonderful event and lots of great folks we are looking forward to seeing what everyone is bringing.
Here's a front/back picture of the completed speakers I'll be taking. These should be of special interest to all my friends who are into DIY speakers, affordable speakers, high sensitivity speakers, full range single driver speakers, and open back speakers. These combine all of the above into one good sounding pair.
Fred, What drivers are you using? Bob
Bob Brines wrote on Sun, 31 March 2013 21:19 Fred, What drivers are you using? Bob The full range is a Dayton Audio PS220-8. The subwoofer is an Eminence Alpha 15A.
Hi All, Looks like some great stuff. I thought I heard last year that folks were going to bring pro gear...amps, guitars etc. If so I would like to have some of you critique my headamp. It might be a dog (or not) , but then everyone has to start somewhere. A clear departure from the hi-fi stuff I have been doing.
Fred, your OB's look fab!! Can't wait to listen to them! I am bringing two commercially available OB's along with a modified KT-88 based integrated (triode and Pentode capable) & a modified 845 based SET integrated. Plus the OPPO player. Should be fun! Looking forward to seeing every one there! Best John Busch

Fred...Bringing one of the OB's shown at the web site. That would be the commercial version of the Ultra. There is also a upgraded version not yet posted at the web site I call the Ultra Plus! Dual woofer with the Current Seas 8" dual cone. Will up date the web to show both hopefully next week after the photo shoot. So it will be the Ultra & Ultra Plus! both in commercial trim. Look forward to seeing you at LSAF 2013! John
We have 150 AudioXpress magazines to hand out at the show. So spread the word: First 150 guests Saturday get the magazines. We'll save 'em 'til Saturday morning, but they'll go quick. One of our regular exhibitors - OddWatt Audio - is featured with an article written by Bruce Heran on their PoddWatt Series II amplifier. Timing couldn't have been better.
Hi Thanks for the kind thoughts. It would be even better if when they redrew the schematic they didn't introduce an error. Most astute tube builders would find it, still.....
I hate when printed media goes out with misprints like that. Seems like it always does, a misquote or something. Just bugs me! But at least it's in print. You can point it out to everyone that comes through your room. That way they can make note of the addendum, and get it straight from you! After geting the magazine for free, no less. Now that's service! And while I'm thinking about it, I'd like to ask you to sign a copy of the magazine for me. I'm kinda sentimental, and I'll always remember this year's LSAF with my copy of the magazine.
Hi Wayne, Just save me a copy. BTW I have a pair of amps for you. My personal set of KT120 mono blocks. These were just upgraded with FT-3 Russian Teflon caps.
Groovy cool, Bruce. Lookin' forward to it.
OK. I don't do rock. I don't have any feel for rock. I don't own any current (this century) rock. However, I feel the need to have maybe a half dozen cuts for demo purposes. Could I get some recommendations of songs that might be appropriate in the LSAF setting? Thanks, Bob
Bob, I should be there Friday morning. As it happens I've been on a sort of retro Rock-N-Roll kick of late taking a break from my usual Jazz choices and sort of reliving my youth so to speak. I will be bringing some "Classic Rock" CD's and you would be welcome to rip them any and all. I assume that you will have your laptop front end you used last year..... I'll look you up when I get there Friday morning. John Bower
John, Thanks for the offer. I will be getting in ~3:00 Friday, and Bill Currier will be coming with me. Classic rock I have. Fleetwood Mac: Rumours, Steely Dan: Aja, Led Zeppelin: Mother Ship. What I am looking for is some 21st century stuff. Any takers? Bob
Hi All, Rodney and I will be there Thursday night. We hope to do most of the set up the same night. By Friday morning for sure. Vinyl and CD/DVD sources. Light jazz to Pink Floyd. Or bring your own music to us. Amps from 5 watts to 45 watts class A per channel. See what our tubes can really do. We look forward to seeing all you good people again.
So Bob are you looking for some Green Day, Wallflowers, Linkin Park, Jets, Goo Goo Dolls, Nickleback, etc. Can't help there. I thought that they quit making Rock music some time in the '80's and that everything that came after was just bubble gum pop.... John. I'll still be bringing some Doors, and Santana, and some Jazz to... Not sure what all, but will decide when I pack to leave. See Ya there, John
Oh, well. I guess that I can always fall back on Pink Floyd. There hasn't been any decent pop music in this century anyway. See you Friday Bob
Well, it looks like I'm gonna have to play taxi service to bring the oldest back from college that weekend. May is always a bad month for me. On a side note and an observation: If I have to listen to only jazz or classical at an audio show, I'm most likely not going to come. I own some, but it's mood music. I've noticed that when I've asked to play an actual rock or blues CD/album that wasn't on the "approved audiophile" list that there was instantly an aire of tension in the room. Not all rooms, but the majority. Oh, it'll get played, but you can feel the apprehension. I guess I'm more musically spread out than most as I've only found two genre's I usually won't buy, death metal and rap. That, and I refuse to limit myself to just audiophile pressings or uber quality digital. Life's too damn short to be that picky. My $0.02
I've selected the equipment I'll be taking to the LSAF. It includes a Cambridge Audio Azur 840 CD player, a Parasound P3 preamp, a Belkin power conditioner, OddWatt Audio OddBlock KT88 monoblocks, OddWatt Audio PoddBlock EL84 monoblocks (not pictured), and "The Chairs" full range single driver open back speakers with powered subs. Oh, and I almost forgot, a case of Shiner Bock for psychoacoustic sound enhancement.
I'm looking forward to hearing it Fred. I do have a question though, I was under the impression that these were going to be active speakers. When you posted the last set of pictures, I noticed what looked like a crossover filter on the "seat" of the "chair" pictured. Was I mistaken, or did you only use the active equipment to configure the filter? Either way, I'm still looking forward to the show.... Thanks, John
I am bringing a pair of speakers that I designed for Serenity Acoustics. It is their Super-7 model.
Looking forward to meeting you and talking about your preamp that Tony Landry is using. We should be there at around 2 PM Friday. Cheers Anis

Just wanted to clarify regarding the pictures in post 76652 from room 230: That's just my home system including both commercial and DIY equipment. I am not affiliated with Artemis Labs. I just happened to have brought one of their fine phono stages. Probably my fault for not making it easier for folks to tell who the heck I was. I'll try to be more clear next year. Phil
I would like to sincerely thank everyone who visited our room for a listen, we were the odd ones out, being the only folks who were not selling any equipment but participated as consultants for the ordinary Joe. I have uploaded pictures that I took during the show which may be accessed on the following link. http://www.pcreview.co.uk/forums/woodstock-high-end-audio-t4057594.html Anyone is welcome to use these pictures if they so desire on other forums or publications online or print. It would be appreciated if credit is given where due, however if you forget to do that there is no penalty whatsoever
No you weren't. My room sold nothing and I even gave wire away. We did steer several people toward the vender for the kit for the loudspeaker on guy brought and demoed but we received no commision for that. There were several DIY audio rooms. Fred Dieckmann

Fred Dieckmann Fred, My apologies. I take it back. We were not the odd ones then. Anis
My room is definitely commercial, but it grew out of a hobby and is decidedly slanted towards DIY. In fact, for the first couple years my Pi Speakers forum was online, I didn't sell anything, just like you guys. I just provided plans for my speakers, and let the builders gather their own parts from their favorite vendor. Later, I realized there were enough builders that I could get distributor wholesale pricing and exploit an economy of scale to sell kits at or below the cost most people would see buying their parts in single-unit quantities. Seemed like a win-win deal, because I could get a better price for the buiders, and make cheeseburger money out of the deal too. Since then, I've sold several thousand kits. About LSAF 2013, I was kinda bummed that I missed the dinner Friday night. I had visitors in my room until late, well after dinner. The show had unusually high traffic on Friday, and I just let the time get away from me. Most years, Friday is kind of slow with just a few guests. It sort of made it possible for exhibitors to visit with one another. Lots of gear swapping and dialing in happens on Friday. Sort of like when a NASCAR guy blows an engine so another team loans them their spare. Then Saturday is always slammed. Sunday was always load-out day, with a few guests returning to close the deal on purchases, have a second look, and various other "last day" activities. I hope next year to make dinner with everyone. That is always one of my favorite things to do. Now that Rudy's has come up from Austin to Dallas, my vote is we all go there. I love that place! I think another thing we'll probably do next year is to have seminars. Most years, I've done my "Crossover Electronics 101" seminar. We study various crossover circuits schematics along with their transfer functions. Then we play music through a circuit of each configuration shown. Then we change damping and listen again. This illustrates things like the way quarter-wave modes in a horn will manifest in the response curve. We show (and listen to) a second-order filter with and without a Zobel. The peaks that are shown in the transfer functon become audible, so this makes these kinds of effects become "real" for the beginner in this hobby. Other seminars have included tube amp design (from various experts), acoustic measurements (from Keith Larson) and woodworking seminars (from Bill Epstein). They're usually very informative and enjoyable. Can't wait to do it again!
I am not criticizing and hope you were having as much fun as we were. I meet some the local audio maniacs and got to ear some of the speakers I had read about with a good system that I was familiar with. Audio Fred was few doors down and people kept showing up at the wrong room. My wife even came looking for me and went to his room at first. I wish I had gotten around to more of the rooms since I heard some great sounding stuff. Phil Bamberg's floor standing SEAS speaker being my favorite.
Wayne, I hear ya loud and clear. I was really surprised at the traffic this time, I missed out on a few rooms I was sure to visit, yours was one of them. I will make sure next year I be in your room for a listen. Two years back when I visited LSAF for the first time I did pay a visit to your room.

Fred, Oh heavens, I knew you weren't criticizing. I was really just reaching out to you saying, "I hear ya, man!" Anis, I remember you from last year. You were talking about how you were gonna "suit up and show up" as an exhibitor in 2013, for sure. And you did just that! Great to see you both. Kinda love that show, it's definitely coolness shared between friends.

Hi, Everyone, We (Oddwatt Audio) had fun and met some really great folks. I particularly liked to see all the new speakers this year. I have been playing around with some open baffle ones in my spare time. No ... we are not going into the speaker business. However, I do want to thank the folks that helped with evaluating the potential guitar amp we brought. It appears to be a go, but don't hold your breath as it will probably take us 6-12 months to get it out.
