Finished building this today, and I’m far more impressed than I thought I would be. I’ve had a Tumnus Deluxe for several years, now, so I figured with its extra controls that I’d probably prefer that. I’m not sure I do, at this point. Although I still need to do an A/B test with them, I feel...

Got some new 5457’s, and I was finally able to get the voltage correct. Thanks for your help, it sounds much better, now!

Pretty sure it was Stompbox Parts, but it might have been Tayda.

Okay, when measuring between pins 2 and 3 I get 0 Vdc to -.6 Vdc on Q1, at either end of the trim pot.

So, I'm not able to get anywhere near 1.875Vdc on pin 1 of Q1. If I put the ground of the DMM on the chassis and the positive probe on pin 1 of Q1, I get from 0 Vdc to .720 Vdc through the range of the trim pot. I'm confused.

I just finished building mine, and I'm not quite sure how to set the trim pot. Is it for biasing the transistors?

Thanks y’all I’ll look at those threads. Here’s a few pics of the build so far.

Thanks, I might give that tester a try. I did quickly hook up some jacks and a switch to the pedal, and tried it out for a minute. It seems to be working, and I have the trim pot set roughly in the middle of its range. Still not quite sure where to set that. I guess the transistors are fine...

Yeah, I'm aware that there are a lot of fakes out there, I just don't know how to properly test them without the pricey Peak DCA Meters or whatever. I'm not sure I trust this T7 that I've got. There have been times that I tested a transistor and got a reading, and checked it again 30 mins...

I've just built this, but I haven't put it into an enclosure or attached the switch and jacks, yet. I'm curious about the 2N5457 Transistors. How do I measure them to make sure they're good for the build? I have a T7 tester, but it's been acting funny. Most of the 2N5457's I'm trying to...

Finally got it working, thank y’all so much! I removed the daughter board from the equation and used a new Gorva switch. All good, now. Getting signal when it’s on and off.

Thanks y’all, I’ll give it a go without the daughter board. Might be a few days before I can get around to it, but I’ll report back what I find.

Nope, still in the same spot with it. Works when switched on, no signal passes through when switched off. Thanks for replying, I’ve been hoping somebody had some other ideas. I’m already on my second switch with this thing, but I suppose I could try one more. I feel like something’s wrong...

So yes, I get continuity between 1 and 2 in the off position. I’m getting continuity everywhere you mentioned. But I’m still not getting signal when it’s switched off.

I’ll test that out and get back to you. Thanks!

Okay, so when it’s ON, it works! When it’s OFF, it seems no signal passes through to the amp. All I’ve tried so far is running it in front of an amp. Haven’t tried it as a preamp, yet.

OMG thank you thank you thank you. I was pretty sure the problem was in that general area (switch daughter board), but I couldn’t pinpoint it. Thanks so much for your help. I jumped pin C and pad 5. Haven’t done a proper test, yet, but applying power and inserting a cable provided a promising...

Just checked it. Not getting continuity between those two pins. Thanks for looking for me, though! I think I reflowed all those joints since that pic was taken, also. The switch daughter board is definitely looking rough. I also rebuilt most of the pedal at one point, just to make sure all the...

So this is weird. I get 6.7V DC between pins C and D, and 6.2V DC at pads 5 and 6, when it’s on. When switched off, I still get 6.7V DC at the pins, but 0V DC at the pads. When I switched the meter to mA, the LED lit up when testing pins C and D, and it read something like 6.1mA. This is with...

Thanks I’ll give this a try.
