Please anyone can tell me the factors to consider, including burning tank components, when operating old linear amplifiers on the WARC bands, especially 12 meters.

Alpha 76 PAC meaning the 3 tube version.

This blows up on 17M and the Ameritron wont fit. You will need something similar to what Amp Supply used or wind your own.

TenTec Titan One
Dentron DTR-2000

Unwind 3 turns from the top of the choke for 12M, other bands are OK.

ICOM IC-2KL

No idea about the others.



All these amps have factory-type conversions to TEN meters already done. The Alpha has the swamping input taken out. Other than that, all amps are stock.

Why remove the swamping??
