[ICOM] Water damage to PW-1, now inop

[Tony Visco]

Larry,
It is likely that the individual FET's are now unbalanced or it could be a
power supply problem.  Adam would know the details.  For my PW-1 FET
problems meant a trip to Bellevue for repair about a year ago.  Still
working great. Good luck.

Due to a burst water pipe, water poured into my PW-1 while it was operating!

for a few brief moments (less than a minute) yesterday. I immediately
removed the cover, dried the components that had gotten wet, and blew a fan
into the amp for 8 hours to dry any remaining water.

Upon turning on the amp today, all visual indicators seem to be working
properly - all the normal indicator lamps work, bandswitching works, tuner
functions, ACC1 connection tracks the band that my 756 is switched to, and
the fan starts. Everything looks normal UNTIL I switch to transmit mode. 
Then the amp/protect lamps switches to red and the band LED begins blinking.

This failure occurs on every band, regardless whether the tuner is engaged,
and into a dummy load (perfect SWR).

Any suggestions as to where I should look? Or is it time to pack it into a
large box and ship it to Icom?
