If this were the 70's we'd be telling her to get busy with the led solder.

A single PT2399 delay may put you at 20mA+. That's really not so bad, though even on battery power.

The FV-1 will get you 1sec and will sound better than any PT2399 most likely. You can even program it to have PT2399 noise, if'n-u-want.

Great build!

For the rectifier diodes, you want something with a VF as close to 0.33v as possible. You can use BAT46 Schottky diodes as a sub which are 0.35v. Once you get into higher VF, the effect may not work correctly. I tried D9E recently which have a VF of 0.45v and they did not work at all! For the...

Yup, Q1 is your suspect. Audio probe the gate and source pins (gate for input, source for output).

It's not a dumb question. Ground is ground whether or not you are working with positive of negative DC voltage. In the case of an inverter, that 47uF cap is still a power decoupling cap but the + end is connected to ground rather than the - because in that case, ground is the higher voltage...

The j201 and 2n5457 can generally be be subbed for an MPF102 without issue.

I think the schematic is mostly correct EXCEPT Q6 on the schem (not my drawing) is shown as NPN and it is actually a JFET. And, it looks like my layout was erroneously done for NPN. So, what you need to do is: Using a 2n5457, flip the orientation as shown at Q6 on the PCB (so the transistor is...

I looked at this one recently while considering doing it as a regular project. I think there are a couple of errors. I'll check later today and get back to you.

Like benny said there is no switching problem that exclusively requires an SPST. For power on a tube pedal you can even do one better with an SPDT. Use a 1M resistor to ground on the extra lug to quickly drain the voltage off B+ on the tube pedal when powered down. However, there is one...

I'm your Huckleberry. But also, I still laugh about that. What fun we had.

Only Roman Gladiator style will satisfy my bloodlust!

Fight me.
