Marantz 6100 ... anti-skate weight?

how do I go about working on this thing?

As Balifly suggested, the best place to start is with the owner's manual. That may or may not give you some insight into your problem since it isn't actually a repair manual. You might also try the service manual for the Model 6110. There may be enough similarities in the area you need to study.

Your problem is likely to be in the switch which is actuated when the tone arm is moved toward the record. It may be stuck in the closed position and may just need to be cleaned. Even without the manual you should be able to check this out by opening up the turntable and checking the mechanism.

Who has the 45 adapter, and why wouldnt any old round ring work?

The 45 adapter on the 6100 has index marks on it for aligning the cartridge. You don't strictly need it for alignment and any 45 adapter will work for playing 45s.

Can anyone tell me what the weight weighs, and how long the string is if it matters? I have a 6100 missing the same part.
 
I had the 45 adapter with my 6200 and it was used to set overhang, but it matched up with another overhang gauge that I had. They are cool to have, but not necessary. Of course when I sold my 6200 I made sure to point out it had the original adapter.:D
 
The anti-skate weight is 0.8 gram.

I recently bought a super nice condition 6100. Unfortunately, the above referenced weight is missing, so here I am, looking for information on this tiny but important piece of hardware!

I am having strong doubts about the above claim - for one thing, 0.8 gram is very little weight. More compelling is the fact that, according to the manual, the six grooves cut into the horizontal anti-skate shaft represent 0.5 gram increments, from 1.5 grams on the innermost cut to 4 grams on the far end. Can 0.8 grams really generate up to 4 grams of anti-skate effect - in this physical structure? I'm thinking that the person who said the 6100 weight was 4.25 grams was more believable.

I understand the concept of leverage, and I know this case can't be that complicated, but I'm still having a hard time wrapping my mind around this. Anyone care to help me understand this, and confirm/deny the asserted weight of this small item?

Let me start by saying that I don't know what the anti-skate weight weighs. Perhaps someone can confirm what Earl posted. Perhaps that someone is Earl himself if, in fact, he got his figure by weighing an actual 6100 weight.

The problem is, you're not thinking about this correctly. When you set an anti-skate weight you're not setting an anti-skate force of, say, 2 grams to compliment a VTF of 2 grams. You're setting an anti-skate force sufficient to offset the centripetal force generated by the spinning platter and the arm when the VTF is at a certain amount. It's not a 1:1 ratio.

I still have the turn table.

If your turn table needs a 4.25 gram anti-skate weight in order to function properly, then use one like that.

I don't have a scientific explanation just the weight. :music:
