The Fisher Treble and Bass knobs needed for the Philharmonic V Model P-290

Register to hide this ad
Are these knobs different than the knobs of other Fisher products of the 1960s? There are several styles.
 
are the knobs completely missing, or do you just need the brass caps? The caps can be had on ebay.

Here are a couple of pics of the knob off mine, obviously missing the brights.

Well, that's a completely different thing entirely. Thanks for the clarification.

The fortunate part is that it appears that both controls are straight-up dual 500K 2W pots, without using any taps. The manual shows them all being the same part number, R50160-131. The rest of that will be just matching the shaft style in the unit. There are quite a few sources for NOS Ohmite and A-B pots that could fit the bill. From what I can see in the marketplace, many of those used a fairly long shaft, and some had dual/concentric shafts, just to make it more interesting.
