[Heathkit] HW-101, full carrier, no voice when in SSB position & PTT activated

[Andreawinward@aol.com]

Greetings,

I am trying to restore a HW-101, the receiver works fine, the transmitter 
works fine but only on CW. When shifting to SSB and pressing the PTT button, all 
I get is full carrier out, +/- 100 watts Continuous Wave, I cannot get the 
carrier to balance out no matter what I try. The bias is set correctly, but there 
is no idling current in SSB, just full output each time I press the PTT 
switch with the mode switch in either SSB position.

Normal logic would suggest the trouble is in the balanced modulator section, 
but with these old rigs, it seems that normal logic and trouble shooting 
techniques are out the window. Has anyone else experienced this, can anyone point 
me in the right direction? I have read many of the archives, but maybe I missed 
the one referring to this phenomena.

Any help is appreciated.

73, 
John, K3AOT
