Not really you are 100K from the signal and only 1K from 
ground at that point....chances are you couldn't even see it on 
a scope.

Relax it's a lm3046....the recovery amp is a 3080 and the output
amp is a ( good luck finding one of these!) EHD-AP4153 that I
suspect is a NE4153 not that it makes it any easier to fine one. It's
a small pre/power amp I'm sure a lm380 can be hacked in if its bad.
So everythings duckie! Yes?
