Anyway, I love the time and effort that you guys have put into your amps. These things have been truly inspirational to see and hear.

And Plexified has lots of interesting thing to say (along with colorful prose) about magnetics and their influence on sound (look up his old posts) along with saying much the same thing about Ed's OT:RACKSYSTEMS wrote:Jeez the pic was taken some how after I got my hands on it. This is the state it is in now. V1 820/.68 v2 820 330uf. Originally v2 .68 and 470uf supposedly. Stop all this silly stuff it was a stock 12 series amp with 2 changes the 470uf on v2 with a .68. Filtering of that era and a slight change in the feedback circuit. I won't say anymore. Remember you are trying to recreate a recorded tone. Its not how the amp sounded in the room period. Add the signal chain and the bias turned all the way hot and then dropped with the variac and also remember it had a latter jmp output transformer and choke installed at some point.
I assume they are both talking about a C1998?plexified wrote:I believe Ed got the amp with the origional transformers . Mainly because he said Jose beefed up his amps . He was right . Because he blew up the origional ot in his experiments and went to Jose , right down the road . Here Jose put in a JMP output . Much lower impedence , physically larger and would absolutly define 'beefing up ' a 12 series 100 watter . It would be much louder and ballsier . A 12 series is more like a loud 50 watt plexi rather than a Metal Panel 100 watter or Ali chassis 100 .
