Stan - that was super helpful.? Thank you for taking the time to type that out for me/other hams that want to learn by doing (or by destroying).?

After i read the earlier post about the pin to T507 i assembled enough non-panicky energy to actually go and look at the traces in the assembly manual.? Lo, what did I see?? Indeed a direct connection to T507.? I was operating at 7V for a 9V QMX, but indeed over extended period.

The support of you, Steve, and others who have answered my questions over the years since my first QCX build gives us electronically-uneducated persons the readiness to venture forth and enjoy this world of home-finished qrp radios.

It is all very appreciated. Thank you!
