Don,

I've got the follow note written for the 7225:

FM problems: bad ceramic caps:

C909 (may be removed)
C905 ).01 disk (0.02 KO)
C912 0.047
R920 150K (was originally 4k7) if tuning voltage inoperative (high) at
cold turn on.
C110 and 111 0.047 at LA 1265 IC.

C909, C905 and C912 should be replaced on any unit with FM problems.

All that said, you must first make sure that the basic power supplies
are in good working order, and I recall some soldering problems in the
front end of some NAD models, especially on coils, that might need
attention. BE CAREFUL in the front end! Realignment may be needed
after working on the front end that requires a good FM generator, so
that is the last thing I'd mess with, unless you've got a full service
bench available.

My trusty NAD 7225PE receiver recently ran into problems. While listening
to an FM station, and for no apparent reason, I ended up with static. I
tried tuning several different stations, with no luck; all static. All
other sources (i.e. CD and AM) work fine. Interestingly, I selected FM
today, and got a few minutes of radio before it went back to static. Let it
set for 45-60 min, selected FM and it worked again for a while.

I am guessing a dried out capacitor somewhere between the FM antenna in and
the audio source selector. Anyone seen (heard) this problem before? Any
ideas on how to trace this down quickly? Or is it time to think about a new
receiver?

Thanks!!
