fisher 400-cx-2 pre amp what is the market like?


I have my Fathers Fisher 400-CX-2 pre amp in perfect working order. The system was taken down a few weeks ago to replace carpet and Mom has decided not to put it back together, and would like to put it on the market. There is also a KM-60 fm tuner that is also in great working order. The tuner has had two knob covers come off, and one is missing. I need to find a replacement knob face and find the correct method for gluing them on. Dad purchased the system one piece at a time in the early sixties and was the only owner. everything works as if it were day one. Any thoughts?

I have seen them from $1200.00 to $1600.00. What would you consider? Thanks!
WELL I DONT KNOW ABOUT THE TUNER BUT THE PREAMP IS EVERY BIT AS GOOD AS A MARANTZ 7C. SHOULD BRING 2,500,00 OR SO. WILL NEED TO BE RESTORED WITH A REFURBISH KIT. IVE HAD ONE . THEY ARE FANTASTIC PREAMPLIFIERS. MCINTOSH MX 110Z IS JUST AS GOOD LESS THAN HALF THE PRICE.GOOD LUCK!!!
