Tube Rattle, Buzz, Vibrations, etc!?

I'm getting a lot of tube rattle from some brand new winged "C" tubes....Russian made. Real bad. I bought this amp a few months ago, got new tubes b/c of the rattle, and it's almost worse now!?! Any recommendations of a good "non-rattly/low-rattly" tube?
Also,,,,,it read here on this forum that it's best to run 212 HD combo's on 4 ohms. Why? Rattle? Tube life?
Lastly, getting a lot of buzz from the amp....ESPECIALLY with the reverb tank wires (and the footswitch) connected. They seem to act as an antenna. Is that normal? This buzz is coming thru the speakers when nothing is being played....no guitar plugged in,,,nothing. It gets louder the louder I turn the amp. I can kind of even almost hear it thru the music when I'm playing!?!? Normal? Any way to ground these, or something?
I'm looking for a good MM tech in ATL, any recommendations?
Thanks!
Doug
