Well Tempered Reference Arm


Can anyone provide answers to the following:

What is the............

1) Effective length (in millimeters)

2) Mounting distance (spindle to pivot)

3) Offset angle

I'm trying to get this info so Mint LP can devise their protractor for me.

I think from spindle to pivot 9.2 inch or (234mm)and the 20 degree tracking angle for the cartridge.
Dear Mred: I don't know how the WT arm stacks up against the others but being an audionut I had to have a new TT after 15 years and bought a Kuzma Reference TT and 4 Point arm. Haven't A-B them but I like new things and am very happy with it.
Mann,

Thanks for your response but your info differs from Donaudios'(via Wallytractor). Where did you get your info?
Rauliruegas,

Re: Stanalog..........I'm very frustrated because I've tried many times over the last 2-3 months (both phone and Email) to contact them and have gotten no response. Any ideas why??
Mred,

I also have an interest since I have a Well Tempered reference arm & table also. Note that my table goes back to the square motor design.

I also have a Wally Tractor and Wally sent me one that had an effective legnth of 235mm, same as a Graham. My spindle to pivot measures about 217mm. Note that this is a pain to measure since the pivot is where the threads intersect.

I've assumed that the effective length was the distance from the pivot to the stylus tip - thus this measurement depends on the cartridge that you'd be using. - I think! I'm using a Shelter 901.

As far as offset angle, are you referring to the angle of the cartridge mounting head? If so, I measured that angle at 68 degrees.

Hope this doesn't confuse any further. I'm going to try to remeasure again & I'll let you know what I come up with.
