[Elecraft] Help PA gone crazy

[g3pjt]

Hi

Thanks for reading this.

Turned on and pressed the key and the warning 'PA hot ' has come up and then
'Hi refl' and the sidetone sounds garbled. The Fan has come on full.

Done some checks.
The voltage on the temp sensor point is zero but so is the voltage on '5B'
on pin 15 of U1 - so that is consistent. No error is shown on the PA menu
entry.

Now after about 30 mins the fan has just gone off and all seems to have gone
back to normal.

Set up is K2 ( version 2.04p 1.09) KPA100 ( 1.06), KAT100.

Any ideas ?
