I picked up a couple of technics 1200 m3ds off of ebay, and I'm having some very annoying problems with them that are seriously degrading audio quality and consistancy.
Problem one: One of the turntables sounds OKAY, but the right channel comes in too strong and it doesn't track well. The Anti-Skate is alll fucked up, it has to be set to zero and even then it still wants to drag outwards.
Problem two: The other turntable is just fucking pissing me off. Something is seriously wrong with the grounding, because i can hear myself touching the RCA cables. The bass doesn't come in, and the signal is really weak. The tracking on this one is also shit.
Any advice would be helpful. One of my friends has some identical tables and he can help me out. I admit I'm pretty new to using good ol' vinyl (i have like 21 now) and any advice would be appreciated.

I had a lot of the same problem and took them to a Technics authorized repair guy. I didn't wanna risk fucking about with all those electronics, just get it done right

maybe you plugged the rca cables into a cd one instead of phono? Turntables give out a weak signal and need to have a amp. Or with the djx700 switch your Phono/Line switch over to Phono

To address your anti-skate problem -- it all comes down to the screws on the top. They are torque screws which means that you need to adjust them properly in order to avoid the "pulling" that you're getting. Play with them a little bit and I assure you the problem will be solved.

If the needle slides over...you put more weight on the tonearm

for the record, anti-skate does NOT have to be at zero, this position is mainly for scratch dj's . A rule of thumb i always followed was to set it equal or below what your tracking force for your tonearm is..
btw, did you balance your needles properly and set enough tracking force?
As for the humming, it could also be a bad ground..

and fuck your records right up.
if the needle slides into the middle the last thing you want to do is that. it is an anti-skite/horizontal weight problem.
veezee, anti-skate is BEST at zero for all types of djing. it does say keep it at the same as your counter-weight in the manual, but this is for normal play. as a mix dj, you probably move the record backwards and forwards a lot more than you think much with only back-cueing, and every time you move the record backwards with anti-skate on you are scraping out one side of the groove, which is why anti-skate should always be at 0 when djing.
i could give you a more technical explanation, but i can't be arsed at the moment

this has nothing to do with your TT problems, but you sould use spherical styli instead of elipticals for DJing, yes the Es have a little better sound, but they wear our your records twice as fast.
