[AMPS] Blow TL922

[Helmut (DF7ZS)]

HERE IS THE STATUS SO FAR !!!

Hi there.

Thanks for all these useful replys. I never used such a
great source like this one.

I located the zenner diode as defective but it takes
about 1-2 weeks to get a replacement. The L2
between grid and ground is also defective. It's a
470 uH one wich is not easy to find. That will take
also about twoo weeks.

I keep you updated ....

73sss
