Hi,
I removed this amp from the EFOS2 Maser as it was intermittent.
Of course now I can't get it to fail on the bench!
I have fabricated a new PC board to replace it and have the components on
hand.
Note the 12pfd cap on the collector .
Some notes I have indicate is select at test and that is it a glass
capacitor.
The as built unit has a johansen 50pf that looks to be an early version
of surface mount with leads soldered on.
How do I determine what value to install on the new amplifier?
Cheers,
Corby
