Russ;
I was thinking more about the quality of some of the parts they used, such as the IF and discriminator transformers, they appear to be the same makes and styles as those used in millions of AC/DC sets and run of the mill radio-phono combo units from the late 1950s and early 60s, the ones with the crappy silver mica sandwich capacitors in the bottom. This is what the Miller/Automatic K-tran style ones have for sure, the cone topped ones might have something similar, but again nothing high end about them even if they used ZPO ceramics or discrete silver micas inside. The switches and pots, again run of the mill stuff, probably made by CTC, Centralab, or one of the others, I don't see any Allen Bradley stuff in there, the band/function switch is your standard phenolic wafer construction. All of these components probably work fine , they certainly do in many other articles of consumer electronics, but Fisher was supposed to be premium priced, and so are many of the asking prices for these units today. I would expect that something that was premium priced should have used industrial grade or mil spec grade components all through, the only thing that I can see that is above average are the tube sockets perhaps, and the Phillips mustard caps, and that it should be ready to play with a minimum amount of work, such as replacing the electrolytics, not a rewire of the power output stages.
