    I recently built a battery box for my 1980's Radio Shack PZMs with
    instructions from:

    http://prosoundweb.com/recording/tapeop/buildmic/buildmic_16_1.shtml

    Before building this battery box I removed the existing ones and
    soldered XLRs to the cable coming from the PZMs. The only difference
    to the instuctions in the above link was that I used a single all-
    metal project box for both left and right channels. The poblem is
    that the box makes a noticable humming sound and aloud shrieking
    sound when they are touched. Does anyone know how I can correct this? Thanks
