Maybe wrong so treat this with a grain of salt
I think these are the power and output trannies for a Hammond Organ Power Amplifier Type 6.
AO-16670-5 Power Tranny. [email protected] for a 5U4 rectifier, 430-0-430 HV, 6.3V @ ? amps.
The 6.3V supplies heaters for a quad of 6V6 and a pair of 6J5 for the phase splitter.
Power supply was choke input and included a back bias wiring scheme to give 280V B+ and -16V bias.
AO-16682-1 Is the Output tranny for PPP 6V6. Probably about 4K Raa.
Maybe someone else can confirm or correct the above.
I'm interested in the output trannie. Do you think it was for an amp with a quad of PP 6V6's? I need an output for a pair of 6V6's. I"m not sure if that 4K value might be a little low. Trying to use in guitar amp but not sure how well that would work out.
page 120 which has page "3-41" on it. The copy quality is not great and so not absolutely sure of the tranny numbers. The file is >6MB. There is a full pdf version at that site which is >60MB, I don't really expect it to be more readable.
