Hello friends (and Dieter...)

I have an a124 that doesn't work:
resonance is audible only after 8
and the mix on the low pass mode seems not work at all

I have another wasp filter, and I exchanged the 2 3080 and the 1458 and the 4069
but the result is always the working one, working and the dead one, dead...

are the 2 bc557b picked with special characteristics

thanks

antonio
