The Clap pops

[Barry]

Just finishing up "The Clap" build and it sounds good, but pops when engaging and disengaging

Put a 1M resistor from input to ground, most of the designs here have that as a standard feature but the Clap doesn’t

Tried that not much help, beginning to think it may be the LED

Is it only Slight popping?
R15 - 47K might need to to be 10K

It's noticeable, I've pretty much ruled out the LED as it's popping on and off, and from what I've read LED popping is usually on the on

It could be Capacitor discharge that's why I mentioned R15 .
Only other thing it might be is a Dry joint.
Have you tried the '' Tap the Pedal firmly Up & Down on the Floor '' trick to see if it causes a Pop while it's On!

I'll try R15 to 10k

No haven't heard of that one, I did tap on the components to see if I could find a bad joint

It has worked for me a few times, Are the Transistors in Sockets?

Yes

 

[music6000]

Yes

I don't Socket! When I have, I solder the Center pin. Have you tinned all the Transistor Legs so they have some thickness and make better contact.
Could be your Issue!
You could try loading each transistor one at a time with your Finger to see if the Issue stops!

I've started tacking one leg myself, but I'm leaning towards soldering them in, I had an issue with the Aldrin was a loose transistor

Thanks for all your suggestions and taking the time to post them, I'm definitely going to try them all!

I only Socket all my Op Amp's with the Machined Socket type!

 

[Barry]

I use the Machine socket type as well, for op amps and transistors, but I think these last few issues with transistors and sockets unless there's a good reason to experiment I'm soldering
