[Drakelist] Source for pots?

2012-01-02 Thread Steve Wedge
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?

Still looking...

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.

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...

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.

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...
