Impedance of output transformer in Philco 47-1230

3/6/2009 5:21:08 PMBill VA

Philco 47-1230 is covered by SAMS 22-33. I don't have. If someone has it please tell me the impedance of the output transformer. The p/n is 32-8274. Thanks.

Hi Bill,
6V6GT in push pull need 8K ohms if impedance from plate to plate.

Bill's antique radios will give you all the poop on output transformers.

Thanks Bill and Lewis. Understand OPT requirements. I want to know the SAMS published data.

Hi Bill,

I've only restored 4 radios, but Philco 47-1230 was one of them. I offer my help if needed...Neal

Googling around a bit, I came across a place called Harp Amps. They seem to know a lot about transformers for tube amps.
Might check it out.

Hi Edd,

Looks like my table disagrees with the SAMS. I got it from Bill's antique radios.

Any Idea why that may be?

Best Regards,

Bill

I just checked the spec sheet form Tung-Sol. It indicates that the plate load is not critical, so anything around 10K would be fine, be it 8K or 12K.
