Re: [Elecraft] New Revision of KPA500 LPF TR Switching Rework Rev. E
I didn't see anything on the Elecraft support page about a mod so I put in a ticket a few days ago inquiring about my KPA500 Serial 1503. So far, no answer.

[Elecraft] New Revision of KPA500 LPF TR Switching Rework Rev. E
I have an early KPA500, and it works flawlessly. Is this mod recommended by Elecraft on ALL amplifiers that presently have Rev. D ? This mod requires considerable disassembly, and I don't want to do it unless it is highly recommended. Please state the specific reason for this mod. Thanks.
