Strangest Phono Sound I Ever Heard


First of all, Happy TG.  Yesterday, the strangest thing happened with my TT.  I have a Basis 2001 with a Transfiguration Orpheus, running to a Linn Linto.  I've had this setup for well over 7 years without any problems, although I did change the cart once.  So the other day I put on a record and I get this strange sound in the right speaker, almost like mistracking and it started happening consistently.  I checked all the connections and they were noiseless.  I even changed the input on my integrated amp, which works perfectly with my digital.  So I figure maybe the cartridge is messed up so I change the cartridge and when I am doing the alignment, I notice an excessive amount of anti-skate, even though I have it set to minimum.  So I take the counterweight off the anti-skate and it seems better.  I install the new cart and It is making the same mistracking sound in the right channel. Plus, I am getting a sound that sounds like a motorcycle speeding up and slowing down in the right speaker.  It is definitely not a 60-cycle hum.  It sounds like a recording of a motorcycle varying in speed.  I shook all the connections and nothing was loose.  The weirdest thing I've ever heard out of an audio system.  Any ideas?  Again, have a good holiday.

@apogeum - Good catch.  I reversed the tt leads and the same sound stayed right.  So it has to be the Linto I think. As for the anti-skate, I checked the tonearm leads and the cue and I didn't see anything.  I ordered a cheap $129 Pro-Ject MM/MC phono stage from Amazon just to totally eliminate the Linto while I see if it can be repaired or it's not worth it.  It's a very decent phono stage on the used market. 

So I got the $129 Pro-ject phono stage from Amazon and everything works perfect.  I'm sure I'm the only one in the world using a $5k cartridge with a $129 phono stage.  I'm a little embarrassed to say it doesn't sound horrible at all. You should get one to keep as a spare when your 10k unit craps out and you send it out for repairs. Thank you for your sound suggestions. And @axpert - you're absolutely correct.  Basis is a top-notch company, but before I send the arm into them for a checkup I figured I'd ask if anyone here had the same problem. BTW - AJ had a very different approach to setting anti-skate if you watch his DVD.  He made some great products.
