Right Channel louder than the left

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.

Before you truck tht pre-amp down to a techie simply switch the tubes in the phono stage from left to right. See if anything changes. If not, tubes are not your problem.

I actually just switched the input source to CD and the levels even out. I dont think its the preamp.

Dravid1, Doesn't the pre-amp have tubes in the phono section? If so, those would be the tubes that were referred to. Your other sources would not 'see' the phono stage tubes in the pre-amp so it is possible that those could be the problem even though your line stage tubes are fine. Just change the tubes from side to side, or better yet if you have some new tubes just try replacing them. If you don't have any extras, you should! :-)

I just switched the wires on the cartridge and the levels are OK. I switched them back and it looks like problem has gone away or is barely perceptible. Maybe a faulty connection that got resolved?
thanks for the help
