Sorry Bruce, I appreciate your help as well and dint mean to call you Evan, not that that was an insult by any means HI HI

Okay, so... PTT voltage measured at R14 is about 4v and remains very close on power drop.
The Supply to R5 measured at R5 is 3.5v and also remains very close on power drop.
?
In a new experiment, the plot thickens... I dug out the qcx-mini. Viola, this radio does not exhibit this problem with the amp.? And the amp gets a ton warmer considerably faster.
?
So, now thinking the amp is okay and the issue is with the QCX+ But what confuses me is that the QCX+ by itself behaves normally. Only when connected to the amp do I see the issue.
