With those TIP transistors.....in my home they drive me crazy...i had to install 470 picofarads from base to colector to stop them to oscilate.

Eva told me that once.

Nice amplifier, thank you to share that with us.

regards,

Carlos

Yes, that one the problem of darlington the TIP. To need good oscilloscope in order to see to oscillate.
