I have a slight humming, well actually closer to a buzzing which is just barely audible in the silence of a record.  [Quieter than an ungrounded turntable hum].  I don't think it is a grounding issue as I replaced the entire oxidized ground wire and made sure everything is in working order.  I also suspected it might of been power related but it still buzzes without being plugged in.  I'm currently suspecting the cartridge is not loaded properly (wrong pre-amp).  It still did with with a few different pre-amps I have, one of which is receiver/amplifier.

 

Turntable: Ken-Tech TCH-33

Phono Cartridge: Audio-Technica AT90

 

Cartridge Specs:

Frequency Response 20-20,000 Hz

Channel Separation 24/15 (dB at 1 kHz/10 kHz)

Vertical Tracking Force 1.0-1.5 grams

Stylus Construction Bonded round shank

Recommended Load Impedance 47,000 ohms

Output 3.5 (mV at 1 kHz, 5 cm/sec)

 
Stylus Shape 0.7 mil conical

Cantilever

Alloy tube

 

And I've read somewhere that it is a "Dual Magnet Phonograph Cartridge" if that means anything (other than a typical stereo cart.).  Is this the typical MM or a MC?  I would appreciate Head-Fi's input and theories.

 

I'll be happy when I can get my favorite turntable and cartridge working as flawless as possible.
