Anyone out there got a spare front panel IF Gain Pot for the RX-1?
This little *&%$ is VERY non-standard, having a threaded section
that's almost 5/8" long, so it will fit through that very thick set of
two front panels.

Part Number is B-10-70; it's a 10K linear pot (easy enough, I have
three standard ones!) but that long threaded shaft really threw a
wrench into things.

Picture at: www.moonlightsys.com/misc/rx1_IF_gain_pot.jpg

Already adapted one of my junkbox pots with parts from the B-10-70
pot, but the result is not working very well; the process of
machining, cutting and adapting the various parts is kinda rough on
potentiometers.

Would also consider (as a last resort) buying an entire RX-1 junker
chassis.

Thanks,

Who made the pot? If you can find another of the same brand you can
usually pry the tabs up and replace the resistive element and use the
exoisting shaft, body nad cover to keep the original look.

Mike,

I wish I knew. The thing is unmarked except for the Heath P/N. sigh

Sometimes the brand is stamped in the metal near the mounting bushing
in a very small font. I have a few new heathkit pots somewhere. I will
try to find them to see if I can identify the OEM.

Can you post a clear image of the part on the
news:alt.binary.pictures.radio newsgroup? A flatbed scanner will do a
decent scan of most parts, but it helps to put a couple layers of a
white tee shirt on top to get a light colored background.
