Thermionic deluxe no sound

[Satorion]

Hello

My name is Jimmy from Finland and new member here. Finished my first build but no sound. Sound goes thru the pedal when its of and when i press the left button. But goes silent when i press the button on the right, weird.. Have no clue were to start looking? Any suggestions would be appreciated.

IC1 Pin 7 i still messed up. Check pin 5 again. We're very close to the root of the problem.

Pin 5 measured 4,59v

I'm thinking IC1is either damaged or not soldered properly. Visual inspection of the solder joints on IC1 is req'd. Only other possibility is something connected to IC1-7 is loading it down. IC1 pins 5, 6 & 7 should all be the same voltage.

Ok, will check it tomorrow. Thanks for your suggestions!

Found one problem at least, one of the legs was bent and not soldered at all on IC1. Desoldered and changed the ic for new one just in case. Now when connecting power two of the leds light up which did not work before. But still no distortion, just clean signal that goes thru like before. Still have not measured the voltages to see If they have changed..

Good find, keep looking...

That first resistor behind the 22n cap looks to have very little solder
