The output don't forget is driving a speaker and the bias is set for a bit more quiescent current to give less distortion, I can reduce it to 4ma overall but audio level is less and distortion higher.
So far it's run around 100 hours with no problems, on the second set of PP3s now.
I use GP batteries from CPC, The alkaline work out cheaper in the long run.
Addendum..... Sorry its 63 volts using 7 PP3
