Do you have a pic of the trace side of the board?

What transistors did you use?

Hard to tell but check the 100K resistor to GND at the Base of Q3.  Looks like 10K in the pic.

I used BC550C for both Q1 and Q2 with a 600 hfe value for each.
Q3 is 2N2222A with a 180 hfe value
Thanks

well done and thanks  !
A dummy error. Sometimes you can spend hours looking for the bug...
In general I do not have this kind of error because I measure every component before soldering them. The main errors are bad weldings or bad locations.
Never had bad components issues
It sounds awsome now !
great great blog. Thanks again
