AC motor controller

Reading pages by people who have actually built these things is probably more useful than forum postings by a bunch of people who switch up cheap beer and motors.

This comment bothers me.  I realize that it is hard to judge intent on the web, so hopefully this was meant to be funny?  Pabst is a well known German motor manufacturer.  About ten years after Thorens discontinued the TD124, they chose Pabst to provide replacement motors.  So I don't think Grainger is switching up "cheap beer and motors".


Pfenning was quite clear that he is reasonably confident in his mechanical abilities regarding the build.  Perhaps more so than the author of the DIY turntable site referenced.  Pfenning  was specifically asking for input on the electronics and motor.  That was the focus of the responses.

There was never a _Pabst_ motor for the TD-124...

I consider the Analogue Department one of the authoritative sites regarding Thorens.  Perhaps you'll take a look.

A Papst in a Thorens?

The story goes something like this:

In 1977, ten years after the TD124 had been discontinued, Thorens management worried that it could no longer supply new replacement motors for their once top-of-the-line player.  The solution turned out to be the subject of this article.  Thorens contracted with Papst to adapt one of their "Aussenlaufer" motors to function in the TD124.

Replacement Motor for Thorens TD 124

The continuing popularity of Thorens turntable TD 124 has led us to search out a solution for the replacement motor. We are therefore very pleased to finally introduce adequate replacement in the form of a motor manufactured by Papst.

Unfortunately, due to the completely different type of construction, and an alternative electrical suppressor circuit, the motor can only be operated with one voltage option.

To order, it is important to specify which kit:

3805-200 Kit for 200-240 V at 50 hz (with C = .47 uF) or

3806-110 Kit for 100-125 V at 60 hz (with C = 1.4 uF)"

Cheers,

Yes. Steve Clarke knows his shit. He knows what a Papst motor is.

I do think Josh is getting a little revved up here, but c'mon Grainger, Pabst is beer. The company that makes the motors is Papst. Finding a link for a mispelled search word on Google doesn't automatically make it the American spelling - yet.

The real question here is whether he's sticking up for PBR (he does drink the stuff) or his turntable... 

 

[Paul Birkeland]

Wow, I commented on a post concerning Josh, who drinks PBR, not you.  Josh also has a turntable with a Papst motor in it, while you have a VPI?

Frankly, Grainger, you are on the border of flaming here.  I'm locking this post for now.

Where I stand is with Peebs. This thread is, unfortunately, locked.

My suggestion is for everyone here -

Remember this is a hobby, not Congress. If someone rubs you the wrong way just ignore him.
