HD1390210 picks up radio stations

What can I do ti filter out the radio stations my HD 130 tunes in? Makes recording with this amp difficult.

Install a line filter? shield the wiring at the first stage (and anywhere else they are microphonic to the touch)? Make sure the grid resistors on the tube sockets are in tolerance? Just a few suggestions, without actually seeing the amp... Please be careful to discharge the main filter caps properly before you do anything...

Somewhere online -- and I can't remember where -- there are documents that show a fix for the RF problem with MM amps. I think it was on the Ernie Ball website, but I can't find it there now.
Maybe one of the regulars can direct you to the info.
