[Drakelist] Source for pots?
I couldn't find a match in Mouser's catalogue for the 500-ohm, plastic-shaft pot that's used for setting the S-Meter Zero on the side of the 4-line receivers. Does anyone here know of a source?

Re: [Drakelist] Source for pots?
Steve - I don't think there is a mechanical equivalent being made today. Best chance is a donor unit. It's a fairly standard (for the time) CTS pot, and may be possible to replace just the element if you can find a regular bushing mount style. You may or may not be able to salvage the plastic shaft. 73, Garey - K4OAH Glen Allen, VA Drake 2-B, 2-C/2-NT, 4-A, 4-B, C-Line and TR-4/C Service Supplement CDs www.k4oah.com Steve Wedge wrote: I couldn't find a match in Mouser's catalogue for the 500-ohm, plastic-shaft pot that's used for setting the S-Meter Zero on the side of the 4-line receivers.

Yeah, I was going to steal one from my TR-3 boneyard special, but someone else beat me to it. I have two in my T-4XB parts unit, but, of course, they're different values. I'm repeating to myself, I will never again remove the nuts from a Drake meter, I will never again remove the nuts from a Drake meter... 73, Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils.

Re: [Drakelist] Source for pots?
Steve, Elecraft uses control pots with black plastic shafts. They sell replacements, though perhaps only to kit purchasers. Elecraft buys from ordinary distributors so these pots are still available. As I recall these types did not have screwdriver slots but you could cut that yourself. Another idea is to use conventional metal shaft pots designed for screw adjustment such as made by Allen Bradley years ago. Our junk boxes are full of them. You could wrap the shaft in black tape for insulation and color match, then use a Sharpie to blacken the exposed slotted tip. Or maybe just spray the shaft with a couple of coats of enamel. From a distance, it should look close to stock.

Re: [Drakelist] Source for pots?
Thanks for the insight on the Elecraft parts - will have to check that out. I found a 200-ohm from the same manufacturer, in the same size, but it did not have those bendable mounting tabs, so I took the bad one and the new one apart and swapped the top mounting shell onto the 200-ohm. It appears 200 ohms will allow for enough adjustment, so my immediate problem is solved, but now I'd like to stockpile a few of these puppies... 73, Steve Wedge, W1ES/4 Live free or die: Death is not the worst of evils.
