I looked at my SB220 parts list. The HV transformer is p/n 54-237 and
the filament/bias is 54-238.
The multimeter is p/n 407-146.
Sounds like Dennis has the correct meters but the transformer is not
the correct HV model (54-1063). Since that is a later number in
sequence, i wonder if it is for the later Heathkit power amplifiers,
either the SB230 or the one that had different tube compliment.
Sorry, later heath #s didn't sitck in my memory banks.
Dennis, if you decide to sell any of those meters, please count one
for me. A spare would be handy, if ever blow out the grid I movement
during a fault.
