Sorry to hear about the hum... I know exactly what you're talking about. I got a cheapo Radio Shack pre-amp, and it hums, too, until I got the ground wire hooked up correctly between the turntable, pre-amp, and the computer card, or amplifier.

Another thing you could try if the power supply is built into the pre-amp you're using, AND if the power cord's plug is not polarized (one blade wider than the other) try pulling the plug out and turning it 180 deg. then plugging it in again. This sometimes helps, since the hum comes from a mis-match somewhere in the power / neutral / ground wiring.

Have fun with it. Hope you get it worked out.

I just pulled the 30 year old Technics sl23 out of storage and replaced the belt. Man, I forgot what I had there. Tommy James never sounded so good. Of course I've never used this turntable when I had Axiom speakers. WOW! Who needs CDs anyway????

littleb,

Philmore?? Good heavens, is that still around? That was the brand name of a crystal set I built when I was five years old. No wonder it has hum!

Seriously, it's likely a ground loop. Try reversing the AC plug on the Philmore power supply, or connect a single ground wire from the turntable chassis to the Philmore chassis or the AV receiver chassis.

Agreed. Anyway, here is the phono pre-amp I use. It's really nice because you can adjust the gain, capacitance and load based on any cartridge whether it is a Moving Magnet, LO Moving Coil or HO Moving Coil. I purchased mine off of Audiogon with the Power Suppy for less than half of the original price.

I was really just kidding about the CD thing. Basically, the only reason I'm still hanging on to the vinyl is that I have a friend who is a collector and as a favor he will give me an album here or there. It just seems a shame to not at least give them a listen.
