I have one that I bought some years back. These are nice when restored and aligned properly. You will need to get a copy of the Service Manual.

Also look into getting some of the upgrades for this FM-3. There is the PEC and Power supply upgrades. I bought and built the PEC kit and power supply kits. The PEC was a big jump in performance, I still need to put the cap board kit in, just enjoying how it sounds with the PEC, Jensen Copper PIO coupling caps and the Takman resistors in the Audio Signal path on output board.

If you keep this tuner, it will need a lot of work cleaning up and then see what you get with the tubes. Also look to see if there in no corroded traces. Also most likely all the those CC resistors are way off due to moisture. Just be very careful when first firing this tuner up.

The FM-3 is a very nice sounding tuner when they are working correctly. I still have my Fisher KM60 Tube tuner and Fisher 200b tube tuners. On the SS side I have the SUMO Charlie, Mitsubishi DA-F20, and the McIntosh MR80.
