the MILA tube mic preamp might be worth looking into as well. it used to be very well documented on GroupDIY . I have a PDF of it including the power supply and some building notes.

That's helpful, especially in regard to the in/out transformers. Thanks! Can you send me the pdf? Curious about how they're doing the power supply....i've seen some with DC filaments vs AC, some regulated, others not.

I just emailed you the PDF

P-20. This one is a bog standard 1987 preamp circuit but with a ~20 watt 2x6V6 output stage to keep it a little more reasonable in the power department.

hell yeah

goddam son

also just putting it out there that I'd also be interested in both Balls mic preamps & Ampeg fliptop bass pre/DI if these ever seem like projects you are going to take on just sayin

GALAXIAN. Original request was "super blown out but with some chord clarity". Its kind of a re-thought and custom tailored Roland Bee Baa. It is 1) intense, 2) noisy, 3) sustain-y. Kinda like a Big Muff's ragged cousin, but none of that scooped mids business. Mids, baby.

Looks great.

Question: why don't more fuzzed have bias controls? For me, going from smooth to that sputtery sound is a really useful control.

There are a lot of circuits where it’s hard to implement to get that dramatic effect you get on fuzz face variants. eg, big muffs /tbmkiii family. I guess it depends on how the transistors are biased in the first place?
