[Amps] Alpha 76 Hypersil HV question

[Steve London]

I have two Alpha 76's, both 3-tubers. One has the standard transformer, the 
other hypersil. Compared to the standard transformer 76, the HV on the hypersil 
76 seems low - About 2150-2200 volts in standby, and 1700 volts @ 1500 watts 
output. What are others seeing ? The capacitors are the original no-name, 180 
uf, 450 volt variety. Should I be looking at replacing them for increased HV ?
