Pure tube phono preamp

ZP3 will work great for you.  It's a virtually EXACT copy of my original CORNET design (long story there), but with an 0A3 added.  For half the price you can get a CORNET3 new, but it doesn't have the fancy chassis.

Hum Problem with Grado
I tried that too, connecting ground wire to motor (bearing too).  Didn't do a damn thing... In this case, the problem is magnetic, and you have to deal with it very differently.Nice rule of thumb:  If you hear "buzz", it is electric field coupling...
