Hum X for CJ PV-10?

I have a ground loop hum with my CJ PV 10 that goes away with a cheater plug. I don't want to use it that way, and the hum really isn't bad enough to risk it. I'm thinking maybe the "Hum X" might be the answer (kind of pricey, though). My question is, does anyone know the output amps for this pre-amp? The Hum X can only accommodate a maximum of 6 amps.

If you have the original power cord on the CJ, you need to start there as it has no ground wire. When I replaced mine, 20 years of copper corrosion was pretty nasty and it was basically lamp cord quality. Not hard for a DIY IEC plug update if you have the right power tools and protect the transformer. Or an electronics repair shop should be able to do.

Is there a ground screw on the back of the chasis?

Theres a ground screw for the phono but without earth terminal to ground, its a "floating" ground. There are PCB board grounds to chassis at the mounting screws, easy enough to rum a ground wire to one of those from a new IEC plug install.
