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...

My bad - C22 ..

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.

Hello -- Unsure why it's so quiet around here today? Not even a mouse. You've answered most already, at least semi-implicitly. Suggestion would be to make the few feasibly switchable tweaks and listen. Disconnecting power stage negative feedback and add in bypass cap on V4a, and perhaps also adding ...

https://en.wikipedia.org/wiki/Enshittification Best .. What a great article. Thank you! This has analogs in so many fields, actually.. every field I have stood in. "heh" but not like "heh.. funny!". Yes. It's not new, just recently in the news renewed. Though Cory's points specifically about tech-m...

Mercury in retrograde ?? Oh.. you! I saw Copernicus sitting at a fold-out table in a park with posterboard signage. G Galilei is right. Prove me wrong. Aright. So Mercury Magnetics have that restomod aura, though potentially costly. They also have a broad selection of suit to purpose contemporary s...

That would be frustrating all right. You and kato answered my questions perfectly. I have a plan to rebirth this amp into a confusing beast that looks straight but it's bent as can be. There is no way I will do it myself. I need to find an experienced winder with an understanding of exactly what I ...
