thanks for your help!
Perhaps I didn't explain my situation really well (I just don't like writing long posts in fora)
- I built the pedal
I put it on a piece of wood for testing
It played perfectly
I prepared the enclosure
I put everything on place
Then, trying to close the enclosure I squeezed it too much and probably some "naked" parts of the circuit touched each other creating a circuit.As a result too much current passed through the 10 Ohm res. and burnt it.
Obviously it burnt some other parts too in the audio side of the circuit (the TAPFLO part seems to work fine
I changed some parts(10 Ohms, the 78L05, the 330 nF, the TL072 ) with no success. So I am asking which part to replace next
The symptoms are:
-The led works perfectly and changes rate as I tap or move the pot knobs
-With polymeter I found out that the ground(-) of the audio out makes a circuit with the (+) of the audio out. How is this possible?! When I touch the ground(-) with my finger I don't get any sound from the amp.
-I get no sound whatsoever.
Should I change the photocoupler? Is it involved with the audio part of the circuit?
