I just got my new Aikido PC board in the mail today. Man it's nice and heavy and thick. Very nicely laid out with clear numbering and lettering. I bought the 5687 model. Now to assemble it and compare with the other Line Stages on hand. It's pretty big; 10" across.

I don't think you should be allowed to start a new project until you provide some commentary on some of your past mentions. For example: ESP DoZ, Snubberized PS Or maybe you're like me, who have 5 unfinished projects on the go at once.

I think you will like it. I built one with the boards Bas had made up. I use 6n1p or 6fq7 for the input and 6n6~ for the output. Everyone who listens to it seem to like it. I used a cobbled together power supply from bits on hand and when I measured it in response to a post on another board. It is absolutely wretched but yet it still sounds good. I have another set of boards and a proper transformer some day soon I will see what it sounds like with something like clean DC to power it…John

I am trying frantically to finish a gainclone and a pair of Tangband speakers before I leave for Baltimore Thurs morning. Two weeks ago, I had this bright idea to build a system for my friend in Baltimore. The Tangband and gainclone are as simple as you can get, but nothing's easy with me. First weekend was spent on the cabinets and second weekend was on the amp chassis. Hoping to finish the wiring tonight. G.

It came straight out of the junk box. I started with a pair of Allied transformers that I picked up very cheep. With a SS diode full wave, the voltage was a bit too low. Full wave bridge a bit too high. So I fed that into a small .22 cap to knock down the voltage a bit. The rest are bits rescued from a junk computer power supply. I checked the voltage and ripple with a DVM and was good to goIt was not until months later, someone ask a question on another board so I hung my scope across the output. It is down right ugly. Between the transformers, the unsnubbed diodes and the small input cap. The thing rings like the bells of St. Mary . Still using it though. Like Arlo says " we’re just wait’n for it to come around on the guitar again , that’s what we’re doing" I ordered a proper transformer and in due time I will fix it. In the mean time I am working on the 300b amps, putting some of Damir and Bas’s ides in the mix. More on that soon. So who’s boards do you have?…John
