Bill,
Does the 5000 use separate bridge rectifiers for each transformer? I built a
PS using two of the transformers from the Henry 2000 units and used separate
bridge rectifiers for each transformer. The DC from each bridge was combined
and connected to the filter capacitor. I didn't use the filter chokes. DC is
about 5000 volts. I believe the transformers weigh in at about 95 lbs each.
Takes a good set of casters to hold the PS up.
Regards,
Larry N5BIP

I have an Henry 5000 watt. The only difference between it and the 2500 is
that it has two parallel plate transformers.
It also is single phase. Wish I had a good 3CX3000A7. By the way the one
on ebay uses a 5CX1500 pentode not a 1600.
