Hi Guys,
Just wanted to piggyback a question about my GTP 500. It is the FM/AM
preamp.
It's been 10 years since I looked into it, but my GTP 500 has a
problem with the FM, no longer recall the symptoms. I was in electronic
repair I know some products have a common problem. Is there an issue
with the FM that crops up on this item? Such as C12 goes open/short?

Mikek,

The trimmer caps in the front end of the tuner are a common problem
with these units. Replacing them requires a realignment, as you are
replacing the things that you adjust to align the tuner.

I would also not be surprised to see the memory backup capacitors
failing by now.
