Goldmund Pabst motor

Hi Mark;

I sincerely apologise for my ignornace regarding the specifics of the drive motor of your particular Goldmund. Of course, I have heard Goldmunds (mainly at shows), but never having been near one for any length of time, or having studied their specifications in detail, I was not aware that some used a four pole motor fed from poor quality electronics.

Cogging and programme wow (design errors?) do not sound like the kind of performance problems normally associated with high mass designs, at least not more recent ones, which seem to have all but banished this performance bogie. I guess this is the price one pays for evolution, turntable style.

Re obtaining a spare motor, dare I ask if you have attempted to contact Papst? I'm sure there must be someone there who will recognise the spec, if not the part number of the offending item, and hence could put you on the trail of a new motor?

In any event, good luck in your quest.

Regards

Mark

p.s. Out of interest, how do you rate the sound of CD next to the Goldmund? My recollection, which I have admit is from 5 or 6 years ago, was that the Goldmund fairly floored the five figure CD it was put up against!

Please try Papst by all means but I doubt you'll find any more success than I have over the years. They seem to be unable to associate any motor with an application without a motor number and/or part number. Do you have those?

I have numbers. I also was able thru some very creative buying and selling obtain a spare motor in like new condition, so I'm OK for a long time. Thanks to all for help. Mark

Dr. Mr. Bendig, no need to aplogize! Goldmund's power supplies are of poor quality, on par with anything available from Mouser Electronics, let's say for $30 US. I speak from experience. The whole thing with searching for another motor started because my motor was making a lot of noise while starting and a bit less noise when turning. I figured that motor was going, found another motor, paid a lot for it and then decided to troubleshoot the power supply. I found a lot of AC garbage on 24 V DC line. I replaced electrolytics in it (from Radio Shack, $5 total cost, three capacitors) and the noise has completely dissappeared and motor has a lot more torque on start too.
Stylus drag on Goldmund is mentioned also in VPI's article on what they tried to improve on in their TNT tri-pulley system.
My CD player is not the best but pleasing (CAL Tempest II tube unit), I had no chance to compare to expensive ones. In my system Studio/T3 combo sounds (rather, sounded, becuase the arm needs work now) better than any other table I've heard to date in my house and I've heard quite a few: Pink Triangles (many versions), Oracles (many, including Premier), Linn, Mitchell Orbe, EMT, Technics SP-10 Mk II, Voyd etc. I'm using ET-2 arm on it while mine is being worked on and it is not the same. It is a clean and accurate arm, but compare to T3 it does not work with the table sinergistically in the same way as T3 does. The amount of energy that T3 produces is staggering, earthquake bass, and yet sweet. My Studio is an early one with a wooden base and as such has a lot more colorations (or midrange?) than later metacrylate ones. In a way, it is similar to Linn in it's voicing, but better in every respect. Right cartridge is a must, I'm using a Cello variant of Miabi, and it works very well.
I still say (and a lot of people will disagree) but in my home at least the best sound I get is from TV (sacriledge!) (cable) on good broadcast, especially live ones.

Sorry for blabbering. Thanks for help.

To all who are interested: I found some more info on that Papst motor, thanks to a very helpful european member: Same motor (with minor changes) as used in a Dual 704. Later improved version used in a Dual 701/721.
