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 have a Wallytractor for my WTT Reference and it says the effective length is 238 mm. I can't find the other info. Don
Dear Mred: With the Donaudio effective length you only have to deduct/subtract the overhang value to know the spindle/pivot distance, at least that's the way with almost any pivot tonearm.

Regards and enjoy the music.

Donaudio,
Thank you for your help.Any idea how our arm stacks up against better known arms like Graham,Triplaner and VPI etc.?

Rauliruegas,
How do I determine the overhang value?
Dear Mred: Maybe it is a good idea to contact directly to:

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.

Gentleman?,

Thank you all for your responses but it seems I have no consensus answer to rely on ie........

This is why I was hoping to hear from STANALOG but no luck.Anyone have any other way to get in touch with STANALOG??? STANALOG,you out there???????? Check your messages/Emails!!!!
I think, unfortunately, that Stanalog is about done, for all intents and purposes. Good luck....
What makes you say that, prey tell?
Only due to the non-responses you yourself and others have posted. It would appear he's on a hiatus of sorts. I have heard very good things about the wallytractor in conjunction with the WT. Good luck....
Dear Mred: I wonder if you have a trouble with your tonearm/cartridge alignment on the past or today: is it something wrong with your tonearm/cartridge performance?

from this " manual ": http://www.vinylengine.com/library/well-tempered/arm.shtml

it seems to me that you can/could make the alignment but maybe I could be wrong.

Now if you must needs the thread tonearm " numbers " maybe you can/could try to contact Transparent Audio ( Karen Summer. ) that build for years the WT products or to Andy Payor ( Rockport Technologies ) who made some re-designs about, maybe they could help you.

Anyway, with the WT protractor you have the effective length ( from stylus tip on the protrator to the bearing center ) and you have too the " mounting distance ( spindle center to the bearing center )and for subtraction the overhang and you say already have the offset angle. Of course that you have to make/take, with the right measure tool, those measures.

Anyway, it is almost incredible that the world distributor of WT can't answer to its customers.

Regards and enjoy the music.

Yes, most incredible!!! Very disappointing.
i have a same experience,but solved now.so if you want , i can copy my original well tempered arm protractor to you,hope this can help you.
Smotyka,Donaudio,Mann,

Stanalog finally responded to my Email and provided the following:

Effective Length - 228 MM
Mounting Distance - 216 MM
Offset angle - 20 degrees

Which contradicts most of your numbers. What do ya think?
Does anyone have further thoughts?
I'm curious as to how the overhang and offset angle are adjusted, since a Well Tempered Reference I aligned with the Feickert software the other day had a fixed arm mounting and fixed holes in the headshell rather than slots. The client is ecstatic with the results, though.
Essentialaudio, I went thru that painful experience (trying to adjust offset and overhang on a WT Ref tonearm) on behalf of a dear friend of mine, whose only crime was that he wanted to install his new Dynavector 17D3 cartridge, which has a very short cantilever and hence a shorter than normal distance between its mounting holes and the stylus tip, in the horizontal plane. It seems you have to loosen a bolt accessible only from the bottom of the WT plinth in order to twist the tonearm on its shaft, to adjust the overhang. This was difficult, even for two people, given the weight of the plinth, the instability of the WT platter, etc. But even when we were eventually successful, it proved to be next to impossible to maintain the correct adjustment while tightening down on that bolt beneath the chassis. It was not a pleasant experience.
