Voltron

Back of the circuit board is difficult because the wires do not allow enough give (after much effort in this direction) to get a full back-shot. I took a couple pics of parts so we will see if I can upload them or email them. The FET is screwed into the side wall with a thin membrane of rubbery material in between. In the back shot of the FET, you can see that the membrane was sticking to the device and left a layer of material behind when I took it off. At some point, I can try to find any more diodes in there, although I have tried to look before. ironbut is going to pick up the amp today and take a look and see what he can see. I will be out of town for 10 days so this way maybe progress is still possible. Thanks again.

I simply could not upload the originals of these or other shots taken tonight, but at least there is some info to be had. One of these on the back of the large PCB, and the data sheet is in the post above: Two of these under/next to the ES1HTRSPLY: Diode bridge: Four wires on the diode bridge: Lousy shot of the big pcb: Amp pics later.

Good thing you ran across a wimpy male with those long but useless faux-mandibles. The female woulda bit your ass just for looking at her too long. Kinda like being in a nightclub.

Canon EOS 5D Mark II After giving my niece/goddaughter my 40D I meant to buy one of these but hesitated. I kept the good lenses, in anticipation of the new beasty. Frustration over amp internal pics pushed me to pull the trigger. Happy now, although I want more lenses, of course.

Well, there was a fet hiding on the side wall International Rectifier IRFP460 HEXFET MOSFET. The pictures will be posted soon. From a better camera, no less.

I don't own this one, so that is why I chose it on Rhapsody. I have CVB on 45RPM vinyl and it is fabulous. JJ is one of my all-time favorites on most anything. Bjork -- Volta In memorium: Michael Jackson -- Thriller

CBS and the LA Times have confirmed his death. He was lost years ago, imo, but it is sad that he is gone. RIP Michael.

That really sucks, if true.

Horace Silver Quintet -- Silver's Serenade Hey, HowdyDoody, this one was recorded when I was 6 weeks old.

I actually said you achieved failure, not that you were a failure, but thanks for reinforcing my initial impression of you with your whiny response to me. Again, I gave you points in my book for making your first post in the Listening thread, but if you and your thin skin do stick around, post stupid pictures that you think are weird ass and edgy in the Slow Forum thread, not here. Now playing for this judgmental would-be adolescent: Horace Silver Quintet -- Finger Poppin'

Failure achieved in 2 posts. Congrats. Oh, and I thought your 1st post was fine, if not trying a little too hard. As for me: Christian McBride & Inside Straight -- Kind of Brown

I think Antonio was saying you built his B22 although I don't know if that is true either.

Various artists (Belle & Sebastian related) -- God Help the Girl Amazon: "After the success of the most recent Belle And Sebastian album, "The Life Pursuit", band leader/singer/songwriter Stuart Murdoch decided to pursue his dream of writing a rock musical scored for female singers. After auditioning vocalists via Internet contests, he made his choices and, with all members of Belle And Sebastian backing him up, recorded this breathtaking record. It combines the strengths and feel of early Belle And Sebastian records in a broader musical palette, which draws equally on musicals, 60s girl groups, 80s indie, and most of all, classic pop."

Have a good one Julian. Are you still thinking about making it up north for the August 8 meet? If so, I'll buy you a beer. Cheers!

Thanks for the thought, Rob, but the spark happened in a different set of rectifiers than the ones in the PS when the gas tube popped. I have used those rectifiers before, and would find it hard to believe that I had one problem in the PS and then had an unrelated bad tube exhibit that behavior. I was not in Mayberry last night so I did not have a chance to do further investigation or take any more pics. So, you think there is a FET on the back of the larger PCB on the side wall and the one screwed into the bottom is the diode? I can get numbers, etc, tonight I hope. Thanks.

I didn't know there still was a Videogon. That's actually the first place I even bought used a/v gear.

I will take a look Birgir, because the original problem with the former incarnation was that the umbilicals had a problem and the amp would power up once and then not the next time.

That's the bitch of it, ain't it?

Here is a pic of the amp section and I will see if there are others. If Asr reads this and has more pics, I would appreciate them being posted.

Mikhail thought the 6BL7s were the best output tubes for this amp. I rarely used others, so there you go. So the FET is actually that thing screwed into the bottom plate?! It is 4 wires to my recollection, but I will see if that is correct tonight. There are some other similar components screwed to the chassis near the heater supply and over by the other pcb (I think). You want the numbers if I can read them later?

Tube complement on the amp is a variety of mix-n-match options: Gain tubes include 6sn7, 2c51, 5965, E88CC/01, 6922 Output tubes include 6sn7, 6bl7GT, 5687, 12az7, 12av7, 5670 I used all 6sn7s sometimes, 6sn7s with 6bl7s, and most often or all 2c51s with 6bl7s.

Yeah, I couldn't get a great shot of it, but that trafo is in meltdown. There are two windings (maybe?) and they are sliding out to the side in different amounts.

I finally said fuckit and unscrewed all the tube sockets, unglued the bundle of four caps and unscrewed a small binding post (or whatever it is called and popped the top off all the way. Here is the dog's breakfast in all its glory: I also created a flickr page with all the photos I took, most of which suck. Hopefully, this will give people who know something an idea of what is going on. I can confirm there is not anything I recognize as a FET or any other kind of semiconductor chip. SDS-XLR PSU Photostream Other than photography criticism, what do you think?

Kilt Fatigue requires moar gin! Congratulations on your fine scholastic achievement Doug! And further congratulations on extending your schooling indefinitely!

You were speaking per side and I was adding them. I ran 2 OA3 per side (for a total of 4). Thought of that as 300 volts, but it is indeed 150 volts per side.
