Somehow Hirsch's photography made everything sparkle that day. My Fisher 400 is clean, sure, but not polished as it appears to be in the photo.
These receivers show up quite regularly on eBay, right now there are two Fisher 400s there. Expect to pay between $150 and $200 for a working unit, without the wooden case.
The Fisher doctor < fisherdoctor.com > restoration kit and instructions run about $90. This includes replacement capacitors, diodes, and a silicon rectifier to replace the original selenium one (from what I have learned, the selenium rectifiers were used in the early 400s, then they switched to the silicon types.) These must be replaced, otherwise the unit will run too hot and eventually self destruct.
All of the tubes used in the 400 are easy to find and inexpensive, except for the 7868 beam pentode power tubes. The Fisher 400 uses four, they should be in matched pairs. No longer made, they show up on eBay fairly often. Prices for NOS 7868s can approach $50 ea, but typicially used tubes that test good can be had for half that or less.
But beware of people on eBay selling 7868s, I have purchased these a number of times, only to have them test poorly about half the time. You will definitely need access to a good tube tester or you may get ripped off.
Maybe someday someone will start making 7868 tubes again, but don't count on it. The all-glass compactron base of these tubes is unlike any other tube. Some people have converted their Fisher 400s to run on 7591s (similar tube with a different base) and to EL34s, and some even have converted the Fisher 400 to run in triode mode, cleaner but with half the power. But then it's not really a Fisher 400, then is it?
