Ok, one step closer. I replaced the two 10,000uf 71v power supply
caps with two 12,000uf 80v caps I had and now the fuse does NOT blow
when I push the power button. But, I hear a relay click and the unit
does still not power up.



Sounds like the emitter resistor has now failed, so the fuse no longer
blows...
