Fisher brass knob caps

I assume there were two versions of knob caps for the Fisher receivers and amps with this style of knob since I have examples of both on some of my collection. It seems the caps that have the small black dot on the bevel were the first design, and the type with the black bar came later. Anyone ever research this, and was there a year when they switched?

I've mentioned this before. The knob brights with the the little indentation on the outside rim were used on the "B" series receivers, are not reproduced, and are proportionately rare to the relatively short production run of the "B" series. The knob brights with the line on the face were the "C" series design, are far more common, and are reproduced due to the far greater number of "C" series receivers out there (which includes the 400). I don't know if any early "C" series receivers received the "B" style knob brights, I dont' recall ever seeing one. The tuner knob brights are the same on all of them, as they don't have any marking.

In your photos, it looks like you have a set of "B" series brights on a "C" series receiver. Not a bad look, but curious. If those are original, I'd be interested to know what the serial number is.

Those type caps are on my 800B, 500B, X202B and X 1000, both integrated amps are mint and have original boxes, there is nothing to make me believe that the knob caps have ever been replaced. I also have a 500-C with original box, it has caps that had no dot or bar. These even had original type epoxy on the back of them and showed no sign they were replaced. I'm just curious to see if there is any documentation on this.

All I have to go by is what I’ve seen, and all of the evidence I’ve come across says that the small edge indentation brights preceded the version with the line on the face. Catalog images seem to back up that notion.
The plastic knob body also has a marker line on it (or at least it should), but I don’t think it was ever too visible, and after 50+ years whatever paint was in that groove has faded and been covered with dirt.

I have zero explanation for a unit that has all tuner knob-style brights with no mark at all. I’m not doubting it, I just can’t offer a good reason why it would exist.

If memory serves, the X-202B and X-1000 may have continued past the introduction of the “C” series reviewers in 1962 (I think), but they should have started production as contemporaries of the 500B and 800B in late 1960 or early 1961.

I think the only documentation you’re going to get is catalog and manual images.

Who knows if they ran out of one type, and used what they had at some point. One thing is for certain, they all will fall off at some point. :biggrin:
 
Funny that you used the words "Run out".
Because when Scott ran out of the great output tranny used in the 299C, 299D, LK72C, and LK72D, rather than ordering more, they simply switched to the smaller trannies from the 233.
