Oh, wow, that does look sweet! I have a thing for the blue LEDs and the clear plexiglass cover makes it look even cooler!

Let us know how it sounds when you get it.

Is this based off the Starving Student Millett?

I've got an original V.2 millett board with a built diamond buffer and a Millett Max board (both PCB's unpopulated) that I need to start one of these years. I built one of the original SOHA point to point and one of the V.2 Millett's with a Meier Crossfeed. I just sold a prototype Stacker II that I had built, but just didn't have the time to case it up. That was one of the best headamps I'd ever heard.

Shane, Nice lookin' stuff there!

I really know nothing about the amp's topology. It was an impulse buy (a reward to myself for one month of not smoking). Funny thing: I don't have headphones. Laughing I gave away my AKG240s about a year ago. Got to get some new cans. I leaning toward the Grado series, either the RS1i or 2i.....C

Wayne,

I'm feeling pretty good so far. I have a few weeks for my vocal chords to fully heal up. They wanted me to not speak for 2 weeks, but I'm sure you remember I'm not a quiet guy!!! LOL!!!

BTW I've got the parts for a all 16 ohm 4 Pi crossover since I have 2226J's and when I replaced the diaphrams in my Altec 291's I ordered 16 ohm from Great Plains to run my 500hz Edgar round tractix horns. I know that you don't recommend those horns for the 4-pi system, but I have had great success using them!

Steve Brown has built me a really neat 6V6 push-pull tube amp according to some requirements I gave him. Maybe he will chime in with pics and brief description of the amp. It uses the output trannys from a Dynaco SCA-35 amp whish is designed for ultra-linear operation. The original amp used 6BQ5/EL84's, but I persuaded Steve to do the 6V6 with octal tube (6SN7) 1st stage and phase splitter.

He's shipping it out to me next week!

Regards, Ron

Steve does such great work! I've been meaning to get an amp from him too.

Does your neck hurt? Do you have to take special precautions when eating? Or is it specifically just vocal chords, so no talking?

On the Edgarhorns and my crossover, it's just that my crossover is designed specifically for waveguides and other CD horns. When using a horn that has collapsing DI, the top end has a little too much sizzle, on-axis. If you sit off axis, it will sound right though.

Hey Ron,

I hope you get to feeling better soon, sorry to hear that you are not doing well.

Bill, I quit smoking 32 years ago, and resemble the guy in the SS Fat Guy dingy.
Eating is an easy thing to do to replace a nervous smoking habit.

Stay the course guys, you will be so much better off in the long run.

Norris

Yeah, he makes nice amps. The beauty of it is he cares alot how the end result turns out. I have seen him breadbord a amp and just as quickly tear it all down if it don't meet his very high expectations!


Does your neck hurt? Do you have to take special precautions when eating? Or is it specifically just vocal chords, so no talking?

Not when they took care of me in the Cincy VA. The first time the VA in Cols attempted the biopsy/surgery, they were unsuccessful. Not to mention my jaw all the way up to my ears were in pain for 3 - 4 days like someone used a crowbar on my jaw!


On the Edgarhorns and my crossover, it's just that my crossover is designed specifically for waveguides and other CD horns. When using a horn that has collapsing DI, the top end has a little too much sizzle, on-axis. If you sit off axis, it will sound right though.

I use a little less EQ and a lower level on the horns and make sure they are exactly at my ear heighth and toed-in to me exactly for position. It is a very small "sweet spot", but very rewarding when you get the amps and crossovers and speakers just right!

Regards, Ron

Didn't work when I got it. The LED would vary in brightness and no sound. Refund issued right away, so I was pretty happy about that. The amps then went up to almost $90......pass
