V1 - 6.3V - filament high current, about 25 amps to support all the tubes
V2 - 25V - Bias?
V3 - 60V ?
These two are probably bias supplies, one for the top tubes and one for the bottom?
V4 - -120-0-120V ? Definitely output section, you'll need about 2 amps
V5 - -260-0-260V ? Driver section, probably 50mA will do the job.

Thanks once again. How exact do the voltages need to be? Could I get away with, say 250-0-250 in place of 260? How about the bias voltages?
250-0-250 would work fine.
The bias probably has to be pretty exact.
Great - I sent an email to the folks at Antique Electronics to see if they had any suggestions for a transformer combo that might fit the bill.
