[Collins] help needed

[drleborgne at aol.com]

Dear collins aficionados: I am in the process of recondicion a 32-S1 ( I am no expert)  Voltage, resistance and signal 

tracing are Ok and adequate signal gets to the grids of , power tubes, but can not obtain grid meter excitation  nor

can I get power out, I have changed a burned resistor, and measurements and close inspection look good.

What could be hiding there, what should I look for ?. Thank you.    KI4JRY   martin
