[Elecraft] K2 no power and low receive audio

[rhapak]

My K2 has the SSB option as well as the Noise Blanker.
The radio functions normally for a period of time then the radio has no
output power and the receive audio is noticeably lower. There is no output
power on SSB or CW, on any bands.
If I shut it down for some time and then turn it back on, it functions
normally again for a while, which leads me to believe my problem occurs when
the radio heats up and returns to normal when it cools down.

Before I start blindly troubleshooting I would like to have a plan.
Any suggestions on what circuitry would be involved to look at first??

Any help would be appreciated!
