Greetings,
I am attempting to commission an 2 meter 8877 home built amplifier.
As I did not do the construction I have to reverse engineer.
The mechanical and electronic construction do look sound and according to
the schematic I have with the amp.
There is about 2,200 Volts on the anode and 4,7 Volts on the filaments.
Problem is with or without drive I get to see not Grid or Plate current on
the meter (which is functioning).
Also I get to see the RF through but when I initiate the AMP the RF through
decreases and no setting will get any response.
Other than the tube being damaged what else can I look for to be the
problem?
Any tests I can do on the tube?
