>Hi Marty,
I'd suggest that you look at your resistors in the metering
circuit. If they have change value, then your bias setting will be wrong
and your output will be low. Make sure that you don't
have a bias supply problem as well. Bad filter caps will do the same thing
to you. Been there,
done that, got the tee shirt`
Thanks!!
