Heathkit DX-100..no grid current
 

Hi..
I have a DX-100 that has no grid current.
The meter readings show '0 for grid.
'110' volts for Plate
'740' for Volts.
These readings are also when I depress the morse key..no change.
I checked the key and the connections are correct.
The transmitter was working perfectly before a move about 4 months ago.
Any suggestions appreciated...John
