Dave:  Excellent  !!
   That is exactly the level of information I need to find what I assume is
bad transistor or two.  I love these power supply problems in this vintage
gear. It fits so well with my skill level coupled  with the stock of diodes
and transistors I have accumulated over the last 30-40 years.

dirty 'manual on the floor' shot of the power supply schematic to get 
you going meanti
