Continuity or audio probe check from point to point, then? At least up to the dpdt For the dpdt question, I wouldn't think so, but then it's type 1 and 2 on-on-on, so... Maybe?

Could not find a silicon combination that got me down to 2.5-3v for q3 Subbed in the mp38s. I think Q2 was 76 HFE and Q3 was 104hfe. A lot of the octavey qualities were gone as well as some of the middy grossness I got with the silicon transistors, so I guess germanium it is for me. I might...

Don't forget to change your thread title to "SOLVED"

Wowwww gotta blang up every little thing

Dangit! That's probably true. And me and my reading glasses need all the help they can get.

Hahaha! I'm sure it was very collegial. With me it's all about the breakfast Sorry, my finger strayed onto the post button before it was finished

Not that anyone particularly needed this update, but I came across @jcpst's build report where he stated that PPCB had the cool audio THAT2159 chips in stock. Needed some germanium mp30s, so why not? Well, for whatever reason, this fixed the problem. I think the compression is a little tamer...

Well, ordered a new (clear) breadboard with potstickers (the screw terminal doodads). Q3 was 5.4v, Q2 up to 4.6v Sorry on the delay, I had forgotten to measure. Got my MP38s, so I'll try to sub in after I also find a si transistor that gives 3.5 2.5-3ish at Q3. I might have to futz with the...

Clear is not common? Asking out of ignorance. I think I've been abusing it by shoving my potentiometer legs in there. I did not measure Q3, just auditioned by ear, but for you, dearest Charles David Bones, I will.

I breadboarded the circuit with some ge 2n169, about 60hfe, but it sucked. Unusably gated and spitty so I can definitely attest to the importance of the transistors. I know I could have futzed with the resistors to get the gain up, but I decided to do the easy things and sub in some higher...

Out of curiosity... Why germanium transistors, particularly?

Success! Thanks, folks! It ended up being a combo of braid, solder sucker, and gentle persuasion that did the trick!

Yeah, I already tried that twice, but no go and now I'm paranoid of frying the pads. Thanks, though, I appreciate the suggestion

Thanks, folks! Will try your suggestions--I forgot I have desoldering braid, will give it a go. Desoldering needles is a first for me! Dovetails--I totally would have gone the snipping route, but the transformer body is sitting right over everything. I'd have to destroy it and knowing me...

I have a very stubborn 6-pin transformer that won't GTFO of my Neurocyton board. I already had a Neurocyton board that sounded like ass, so I went at it again with a new board, put in the MMBF JFETS in ascending order of IDSS, took special care to solder everything correctly. Aaaaand, being a...

That sounds pretty rad. I will definitely check it out. Might be a while, though. I have a backlog of PTP projects: Boneyard (BY) diamond peak, natch Ok doomer (priority downgrade after breadboarding) Nein fuzz Moonn she Ra Figbuster BY fudge factory BY tube Bender deluxe BY hellbender...

Very amp-like and very responsive to/ expressive of guitar elements. Big range of gain from light edge of breakup to gainy clipping. Can do tight chugs, can do doomy fuzzyness. The bass and treble knobs are key.

Well looky here at what I made this evening with some sweet and massive mojo parts kindly gifted to me by @jwin615 that he acquired from a defunct police radio repair shop. Lots of crazy things like an N-D MOS (???), capacitors rolled in paper, and transistors I've never heard of. And very...

Good to know even legends have their off days.

Update on the fizz and the J201s: I really disliked the fizzyness, so I desoldered the j201s and tried switching the order. Still fizzy. Then I put in some sockets and tried doing substitutions with through-hole J201s (~38-46 IDSS--my through-hole j201s by interfet are much more consistent...
