[Hallicrafters] SR-150 Low output

[K4PRF - Burton Pratt]

I am the original owner of this SR-150 transceiver and just hate the 
idea of putting it out to pasture.  It just will not make power in 
either SSB or CW.  If I unbalance the carrier it will make power which 
leads me to believe that the final section is functioning properly.  All 
the voltages and resistances are in the park.  Tubes have been checked 
and substituted.  If I understand the theory of operation correctly CW 
output is controlled by bias.  If the carrier is being cut off by a bias 
problem would that also kill the SSB output?  Any help will be 
appreciated.  I would love to get this old Hallicrafter back in action.

Burt, K4PRF
