Hi,  I'm still struggling with my SX-28A.  It seems I might have need for a replacement Audio  Transformer.
Mine measures unbalanced in the output windings (230 and 166 ohms - they should be about the same to
balance out the hum which I get a lot of).  The book part number is 55B052 but mine has p/n 55B009 which might
not mean anything.  The SX-28, 28A and probably other Hallicrafters which use push-pull 6V6 output tubes
will probably have a similar transformer.
   So are there any parts receivers out there which could part with the Audio Transformer?  I would appreciate
hearing from you.  Thanks.
