Raincoat No signal LED works

[Plaidesaurus]

Built 2 Raincoats and having the same issue with both, which leads me to think I must have put some components in the wrong place. I've built several of these before to give to other players so not sure what's up. I've tried different sets of transistors on both. They all checked out as working on my meter. Even tried some 2n3904s but no luck. Clean signal works fine, LED lights up when engaged, but no sound from either when engaged. Have looked over multiple times but...
FYI, the unboxed board did have transistors in place and was mounted in a box when I demoed. I'm hoping someone sees something here I've overlooked. THX

what transistors are currently installed? The BC549C is CBE and the 2n3904 is EBC.. transistor pinout makes all the difference in the world so you have to make sure you have that correct.

Ok, wasn't thinking about that. But I've tried a number of different BC549C transistors and I don't think that's the problem.

Make sure your 470pF MLCCs are actually 470pF and not 470nF.

Will do and report back. Thx

I'm pretty sure they are 470P. Would I need to pull them from the board to get a proper value reading with my cap meter?

 

[Plaidesaurus]

These were the last 470Ps that I had, and they came from a package labeled 470P. Wouldn't put it past me though to make this kind of mistake.

What swelchy was saying is you would need rotate the 3904s 180 degrees.
Also, make sure you aren't plugging into the out jack. Easy to do when the pedal is inverted.

Yeah, I actually tried that with the pinout on the 3904s correctly placed just a bit ago. No luck. Can't help but think I've put in some wrong value components. Going to remove a couple of those 470Ps and make sure they read correctly.
I use a test box to drop the finished boards into to test so the enclosure is always as it would be on a pedalboard. Still, I have made that mistake in the past. Thx

Sounds like a job for an audio probe now.
