Clean AC power for Project 9 TT

earsandeyes · 2nd November 2004, 11:59 AM

For the the Project TT's you can by a better AC feed.
I asume that it is an stable SineWave Generator with a chipamp as power amp.
Am I correct?
It should be easy to build a frequency controlable sinewave generator feeding a simple chipamp.

Has someone tried this before?
What would be a nice-stable-easy sinewave generator design?

Thank you for your input.

Why not forget AC completely, and go DC? Use a DC Scheu-motor, maybe even run it on batteries? I just did on my Pro-ject, and am gobsmacked by the result. Even though it's a different principle, I don't think highly of the motors Pro-ject uses -anymore. So why go through all the trouble when the motor still is s**t?

I agree it would be an interesting alternative.
Did you by your motor from Scheu in Germany or did you obtain it here somerwhere in the Netherlands.

Are any adaptions in pully's belt's etc required?

Thank you for the info

I got it from Scheu, a very nice set, the motor, switch, pots etc. already connected, complete with some damping/mounting material, a roll of string (THIN!!!) and an adaptor. And two sheets of instructions/documentation. Great service! Thank you Thomas!

The Pro-ject motor drives the subplatter, the Scheu is intended to drive the outside of the platter. On my RPM 4 this is easy; just sling the string around the platter. I'm not shure which shape your platter has. As long as it has a straight side, you could use it.

Good luck!

A quick scan on Scheu's website did not show up a seperate motor?!

What type of cost involved?

Thanks again,

Here it is (pricelist): http://www.scheu-analog.de/pdf/preisliste.pdf

As you can see price is € 75, shipment is € 10

I've been using the motor for a couple of days now, and it's safe to say that this brought my turntable to another level...
I was dreaming about building a turntable, but I think I'll stick with this one for a while longer, and maybe try another arm or something. (Ladegaard???)

Greetings,
