I found a great deal on a super10, I like that cart because you can upgrade to the 30 by replacing the stylus. The only thing that makes me a little uneasy about changing this cart is the way the dual headshells are made. Im not too sure how to set overhang and such. The only thing i have to aid in chainging the cart is a paper protractor. I need to get my hands on a service manual because there is a problem with the lift mech that I can't put my finger on by visual inspection, and that would probably make changing the cart a little easier as well. I appreciate your help on this.

Did you try Analogdept.com? They have many service manuals. Is this table automatic or manual lift?

Yes you can upgrade the om 10 to om 30 by changing the stylus, but its better just to buy the one you want. check the price of the OM 30 stylus. You can get the OM 30 complete for about the same if you shop carefully on line. I found that the price of the OM 30 was up quite a bit, around 285 on a lot of sites, a large increase from the 159.00 that I found it for. I was still finding them at 185 recently, I believe it was music direct. I don't know if it is the case here, but many manufacturers "cull" the bodies for the more expensive models. Since your just starting out, go with the om 10 and get the table working.I do not quite follow about the counterweight not going to 2 or whatever...is it the correct one? Invest 20.00 and get a shure scale. If this solves the problem and you want to go further, you have a working unit with new cart. that you can sell for upgrade $$.

i am going to answer 2 questions in this post.. The dial not turning was due to the previous owner over rotating the dial, so after turning it backward all was good. There are no numbers on the weight, they are on the side of the arm.. As for the cartridges, I think I will opt for the super10 just for the price of 49.99. This turntable has auto return I think, but I am not sure. What I do know is that when you push the lift up or down buttons, nothing happens. The arm that controls this seems to be in tact and is well lubed. But without a diagram i can't tell if anything is out of place or missing, although everything looks okay.

I think you will need to look at a schematic or remove the lower plate that covers the interior and look at the mechanism. If it is a gear to gear arm lift then it should be easy to spot. If a electronic lift then you will have to study it. If gear to gear then some kind of pressure band must be used. That may be worn. It would look like a rubber band but small that puts pressure on one gear to mate with the other when the button is pushed. Or a swingarm might be used. You must find a schematic.

I have inspected the mechanism very closely.. All parts seem to be in place. The lift controls are in the form of buttons on the front of the unit. All looks to be in place except for where the button mechanism mates to the arm that should be controlling the lift pin, there is a junction consisting of two gear like swivels that are spring loaded. From looking at it, it seems that one has shifted to the side. I have found the manual in paper form, but am trying to find one available for download. Manualgenus has almost every manual except for the cs508, even the next model up which is fully auto. Looks as though downloading isnt going to be an option so i will have to wait... I am going to go ahead and get the manual and get this thing running.. Ill post the results of this when I get it completed. Thanks for all of the input, it's been quite helpful.

Thought I'd jump in here and add my 1 1/2 cents worth. I've owned a bunch of Dual tables (not this model, though.) Most of them don't have particularly accurate calibrations on the tonearm adjustments. Getting a separate stylus gauge like the Shure is a very good idea.

If you don't have a record with a blank section to test for anti-skate accuracy, set the scale for anti-skate at about 1/2 of the recommended value. Better too little than too much.

That sort of woe sounds simply like a record player going into a 'regular' rather than an RIAA input on the preamp, doesn't it?

no no no my friend, i am a little more savvy than that.. changed rca's, oil and cartridge and the table now sounds decent... i think it was the cartridge causing it..
