    Yes. The value is actually 10,000 picofarads (10 followed by three zeros), or 10 nanofarads.

    Unless the 504, 105 etc are indicators of value why don't you just meaure them with an ohmmeter?

    When you can buy them from Harbor Freight for $2.99 or sometimes $1.99 during one of their very frequent sales it makes no sense not to own one, nor does it make much sense to be experimenting without one.

    I agree. Are the POTs out of the circuit or are they still soldered in?

    If you switch your multimeter into OHMS(RESISTANCE \Omega ) mode, then use one probe on the wiper pin (middle if there are 3 pins) and one on the other pin. (Or either outside pin if there are 3)

    Turn the adjustment shaft all the way clockwise, read the meter
    All the way counter clockwise, read the meter.

    It should go from 0(zero) to something. This 'something' is what you are interested in.
    Typical values are:
    1k or 1,000 ohms
    10k or 10,000 ohms
    100k or 100,000 ohms
    and
    1M or 1,000,000 ohms.

    Here is some info on testing them, and using them:

    here is a page from MOUSER for the 3006P series of POTs:
