Mint Protractor for the Classic Toneram 10.5i-SE

Testpilot

So, what did we learn?

1) Classic JMW S2P distance is 258mm,
2) Overhang is 15mm,
3) Effective length is 273mm
4) Info on VE is wrong

Are you really so obtuse? Or do you have reading comprehension problems?

1) Classic JMW also came with an S2P of 262 mm so my belief was not baseless or impossible.
2) I did not argue about overhang.
3) Effective length is 273 mm for S2P of 258 mm, but would be different for 262 mm.
4) The info on VE was not wrong when the article came out, and is still correct with respect to some VPI tonearms.

What I don't get is the purpose of you continuing to post in an otherwise dead thread and going after me. What are you trying to accomplish? Actually, I don't even care at this point. You made your point; I made mine. Good day to you, sir.

There was a question brought up about the Effective Mass of the VPI tonearm. I did receive information directly from VPI that the effective mass of the Classic 3 tonearm is 11.1 grams. That arm is called the JMW-Classic 3 damped stainless steel tonearm. At the time I received this information I tested it. I computed the resonant frequency with the calculator based on my tonearm, cartridge compliance and weight. I then then tested it with a test record and the frequencies came out very similar. I therefore convinced myself that the effective mass information for the classic 3 tonearm was correct.

For the Classic 1 the effective mass I have seen stated as 10.5 g, 11.2 g, and 12.3 g. No information as to the material it is made of. However, it is very comforting to see that VPI has definitely got better about providing consistent information regarding its products. They've also improved their customer service with regard to answering phone calls. It used to be all but impossible to get them to answer the phone, but this is no longer the case. It seems to have coincided with Mat Weisfeld's joining the business.

I have a new VPI Classic 3 on order. Does anyone know what the S2P is? I've read 258 and 262. Mine is being manufactured right now by VPI. :)

I want to buy one of the AccuTrak Protractor. Just not sure if I need the 258 or 262.

Anyone know?

Thanks,

Mike
