Thanks! I'll definitely try that. So, you want a total of 120R per side including what the resistance the secondaries already measure? I'll check out your thread Yep. Another way to say it is a static resistance at the rectifier socket, plate to plate, of roughly 240R or more including both resisto...

Hello -- Kept meaning to drop in here with some advice from experience. A few years back I kicked off a short thread that's somewhat on-topic:: analysis of a pair of BFDRs . The detail from that I'd recommend is adding a pair of resistors on the rectifier anodes; i.e., the input side. Measure your t...

Hear here. That went without saying, but as you've shown goes even better said.

Almost certainly a well loved late '60s drip-edge Princeton Reverb and a small tangle of pedal board ..

I cannot spot C21 on the schematic...

Hello -- Martin, as usual, on point accusing one or possibly both of those brittle BJTs. Though their failure/death may well have cascaded from surrounding passives. Proactively replacing the electrolytics C19, C20, C21 eliminates obvious probable suspects. A trio of film capacitors would be an inex...

There is also the insulating "backing" fibre board that in sum makes for a fairly stiff sandwich ..

Hello -- If someone wants to post the preamp board dimensions from a blackface or silverface [ ... ] From my 1964 AB763: Overall board dimensions are 14 5/8" x 2 1/2". There are just three bolt through-holes for mounting. These are slightly misaligned across the longer edge. Starting from the power ...

… so i tapped the tube with my finger and i immediately felt that scary current tickling feeling in my hand. I took them out immediately, i assume they must need grounded or something but until i dig more on that they can hang out on my shelf with the 1000000 other old tubes people keep giving me. ...

Hmm yea -- Here's live footage from our NYE show: https://youtu.be/yTmXcRBz3IA?si=roJphsQMY0rIDnXO Hmm, not sure why video fails. In deed, the yoob crew assumed the depth of their surveillance was inadequate and so broke a few things when tagging each copy with a unique crypto key. They now want to ...

I don't actually need the massive gain of EF86, since I play mostly with clean tones. IME there are just some magical harmonics in the EF86 sound that is often missing with 12A_7 preamps. For baffling (un)reason, in the "voodoo of MI amps" bubble, the equation "gain == distortion" and "gain != clea...

Hello --

A cascode maybe? Or maybe not? A TAG thread on the topic.
