Right Channel louder than the left

Hi
I have a Nottingham Ace Spacedeck and the Ace Space Tonearm fitted with a Shelter 5000 cartridge (MC). I find that the right channel is slightly louder (more dominant) than the left channel (this is also reflected in the VU meters of the pre-amp Mcintosh C2200). I was wondering what my options are to correct this interms of adjustments. Would changing the anti-skate work or should I be looking at an azimuth adjustment (help needed on this one) or something else.
Also what equipment would I need to do this.

thanks in advance

I'm not surprised. Did you check the leads on the phono cartridge? Try reversing these leads and see if the channel reverses accordingly. You could have a problem in the cartridge itself.

Do you have access to a tube tester? Cross check the output of your tubes from their corresponding locations in the right and left channels. Something in the left channel may show a significantly weaker or lower output than something in the right channel.

I dont have a tube tester but may be able to take the pre amp into a shop and see if I can use one there. Great idea

I had the same problem and spent time testing my 6SN7 tubes. They turned out fine, so I then tested azimuth using 1khz tones. There was definitely a problem with one channel "leaking" more than the other.

A very slight azimuth adjustment was all that was required. As a result, I now have significantly better imaging and soundstage.

I later learned that my Soundsmith re-tipped stylus is very, very sensitive to azimuth. From what I have read, it is a Fritz Geiger design. This has prompted me to buy a USB microscope, one recommended by by Mike at Continuum.
