[Heathkit] SB-610 solid state conversion

[Greg Mijal]

I say go for it OM!
While your developing your attack plan, I think it would be good for you to 
see what can be done to improve the power supply in order to save the old 
transformer.  They only exist nowdays in a junker unit and many of those 
junkers got that way from transformer suicide.
As a straight up SB 610, they are a real pain to repair.  Problems develop 
way beyond simple rectifier/ filter cap replacement.  As a first repair job 
with BA stuff, it's a killer!
