[ICOM] IC-761 p/s

[Alan Leith]

Interestingly, there seems to be no other problem.  Switching supplies are
notoriously noisy and you're probable right that ventilation would make
things worse.  At best, it is a poor design, but it is what it is.

I noticed the same thing when I opened a failed PS35 on my 751A. I think
it's because the supply is imperfectly sealed and traps moisture. It would
probably be better if these supplies were vented... But then RF hash might
be an issue.

fair bit of corrosion inside.  All of the screws that hold the circuit
boards are corroded on the tops.   They worked OK, in that there was no
difficulty in removing them, but I was surprised.  Is this common?
