Stuart,
My Corsair II does not have a U10 problem. However, I expect it will
someday. Therefore I am doing a "preemptive strike" and developing the
replacement now. I have seen a lot of Corsairs (both varieties) come down
with the dreaded failed U10 problem. When Neil at AADE gets through we will
have a nice replacement display. Neil will make a little money and we
Corsair owners will get to keep our radios running for a much longer time.
The only other problem I see is the MRF458 transistors in the final amp.
However, other transistors close to the MRF458 are being made. I am sure we
can substitute one of those newer transistors.

Jerry, many times an intermittent in any radio can be traced to bad
solder joints, socket corrosion, or bad contacts on interconnection
cables. If nay of those are in this model, you might simply check and
correct those issues and fix your problem. I don't remember if the
Corsair used sockets or not, but solder might be an issue after this
much time depending on the radio's travel history.
Good Luck,
