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?

Jim,

It's been a few years since I posted this, but I haven't done anything with the preamp. I'll be pulling it out soon to sell it and wanted to offer it to you first as you requested.

You will definitely be hard pressed to find a preamp under $6k that can perform as well as the Infinity FET, it is still one of my favorite pieces that will always stick around in my Infinity collection (#100 here). Last I saw a couple years ago they were still selling for $2-4000 depending on condition due to rarity. The hum could be a number of things but is most likely the large can capacitor near the AC outlets. The internal speaker relay also tends to have some issues over time, but is a quick replacement.

I remember that preamp well. We had one at the stereo shop in L.A. where I worked in the late 70s. As I recall it sounded significantly better than anything else we had at the time.
