You could use a 9v DC supply with a voltage inverter to get +/-9 then linearly regulating both down and feeding that past the rectifier, but since most AC pedals are pretty old I can't say I would want to do this without first measuring the rectified voltages off a known 12VAC supply, especially...

I use a TS for tightening high gain tones with TS drive at minimum so IME tweaking the bandwidth/low cut and bright/hi cut caps were the most important. For diodes I find that the speed at which diodes open/close and overall forward voltage matter more than asymmetry but I mostly just wanted...

With the caveat that I might just be talking out of my ass on a legitimately dangerous topic, I'm wondering how the voltage dropped to 170V in the first place, and how R20/R13 is more distorted than R17/R22, when V2B on the schem is the cold clipper- afaik the main distortion stage. Assuming...

Anyone know of a source for C1M and A100k metric through body pots? It's for a vintage stingray preamp clone

When I think of muff tone I think of a black russian and animato in parallel but if I were to build one it'd be a rog 22/7

I'm not sure I get it, wouldn't 844s draw less than an 84 in the same configuration?

Would a 555 SMPS be able to run a JJ EL844 single ended? I might just be reading the datasheet wrong but I just discovered these earlier this week and that nominal 10 ma plate looks promising. I was trying to math out if it could be run off MAX1771s but I didn't know 555s could go that high.

Also has a dry blend (pre eq iirc?) and a bite switch that's effectively permanently on in the original vt bass. Might be worth a separate wishlist entry

Any chance there'd be switches to go between parts of the various versions, or bypass the speaker sim lpf?

inb4 but why: in some styles of metal it's common to use an aggressive gate for an exaggerated percussive effect and run a compressor into it to keep it from being stuttery. A compressor already has an envelope(?) detector so I figured I might as well reuse it. I'm thinking of using the voltage...

This gives me an idea- what if the standalone power module came with a similar way of mounting a tube internally, but as a gain stage or as pinout board or something?

It's a Vox tone stack. All things considered though it's pretty close to fender/marshall relative to cut/boost tone stacks and the other weird stuff floating out there, so it's not unusual to hear the general design referred to as an FMV tone stack. Gonna be a while before I can build one of...

A while back I saw this old article (https://desmith.net/NMdS/Electronics/NixiePSU.html) on nixie psus and theres a section on exotic FETs and beefier inductors for high current nixies; noob napkin math put some combinations into single ended el84 range but all the FETs listed are long out of...

Dang this just made my day- was looking for one back during the peak of the MB RI hype and these used to be expensive af and near impossible to find. Honestly kinda surprised that there's this many still out there.

Dunno if you're counting the more ampless/preamp-ish side of things but I feel like those at least have more creative use and voicing of a greater variety of building blocks, especially with high gain or bass stuff. idk, as someone who doesn't really go for transparent OD or vintage dirt guitar...

Does the SMPS provide enough current to run another tube or two?

Was going to use the separate power jacks for different voltages or passthru, but I'll probably drop the center one for my own sanity lol. That build picture is really helpful, thanks. Do you think there'd be room to move everything up to make it clear both ribs without milling? TBH I'm...

Tayda's 1590DDs are 188x119x37.5 and their 125Bs are 66x122x39.5, at least going by nominal exterior dims. 6 knob PCBs have a width of 2.25in I think? 3x that, converted to mm should be around 171.45mm; even adding a mm or two for space between them it should still fit. I started prototyping a...
