[Elecraft] 1st alignment steps fail. Was: KPA100 oscillation...

[Jukka Tarvainen]

Hello again!

Started to check KPA100 after weekends failure. Voltage tests on page 43
(Appendix G, KPA100 manual).

D13 133 V
U4 pin 8 -23.9 V
TP1 0 V
J3 + lead 1.35 V

Last one failed, should be 0 volts.

What to look for to rectify this? Or should I just go ahead with receiver
tests?
