[ICOM] IC-765 question

[Marc & Tricia Niebergall]

It's looking like it is in the internal power supply.  I disconnected it
and jumped a Yaesu 13.8 vdc and "instant on".  Tried the internal power
supply again and a short "pause" before coming alive.  So, now it is just a
matter of deciding which components are likely the problem.  May start with
all the big electrolytics.  They are pretty old and probably getting
suspect anyway.

Suggestions?
