Replaced 4 tubes plus installed new finals in my HT37, also replaced all 
electroylitic caps.

When I go to the MOX position I can see and hear the relay clicking open and 
closed.

I can't seem to get a key-down indication tho....I tried a hand-key using 
the key jack with no joy.....I tried going to MOX while in the DSB position 
and could not get any indication on the output meter or my wattmeter.

I wonder why I can't get any indication of the HT37 going into transmit 
mode....no output on the meter and nothing on my wattmeter.

All voltages are what they are supposed to be...I get -49vdc bias when I go 
to MOX .

Is there some jumper plug/connection I am missing???

Places to look....things to check???

Guess I am gonna have to check all oscillators/VFO, etc for activity.

Any and all suggestions are welcomed.
