Infinity F.E.T. preamp


I am getting up in years and don't spend the time listening as much as I do playing my drums and guitars. I have an Infinity F.E.T. preamp (blue) S/N 173. It has a slight background hum and I am not inclined to put money into it. Anybody have an idea what it might be worth as is, or will it be worth getting all the bugs worked out prior to selling?  I'm torn because I have yet to hear a better preamp (yes it blew away my SP-6). I now run a Marsh Audio P2000., because of the hum issue in the FET. The Marsh is close in character, but just doesn't do the sound-stage quite as well. Now on a limited income I face reality. The Marsh is close close enough to my old ears, and I hope to pass the FET off To someone who will really appreciate it.

Thoughts?

This is getting very old probably just a dried up cap, if you or a friend can solder, have a look at the electrolytic caps, look for bulging or dried up brow fluid leakage around them. Cap are cheap. Replace the with the same voltage and microfarad (uF)
BTW they have a polarity made sure the new one goes in the same way
I’ve posted up a picture with the caps to look at circled in red.

It's easy to work on both top and bottom come off no need to take the board out to do the cap replacements.
