    I'm rebuilding a very old test and measurement instrument. I need some high quality pots for the repair (5K, 10K & 20K). The instrument was made in Britian, and internal space is very tight. Single-Turn.
    Critical size requirements:
    Pot diameter 3/4" max, Pot depth behind panel 1/2" max.
    Bushing dia 3/8", Bushing length 3/8"
    Shaft dia 1/4", Shaft length 1/4"
    The pots need to handle 2W, 500V (max).
    The leads need to connect to the back of the pot (no room on the sides).
    I'd like to find some wirewound, or carbon wafer (NO conductive plastic).
    I tried Ohmite, Bourns, Vishay, & Clarostat (now Honeywell).
    Ohmite comes closest (Molded Composition), but I'm still looking.
    Anybody knows of any company that might stock what I need?
    Thanks

    *** In case anybody needs to know (it was a lot of time and trouble for me), Maurey Instrument Corp in Chicago, had what I need. So I GOT the potentiometers I needed for my application*** shrtrnd 28APR
