thorens 160 psu

stueyh · 31st May 2005, 02:24 PM

Hello all,

Ive just aquired a thorens 160b tt. Ive fully stripped and rebuilt it to the point Im ready to make a better plinth. I was just wondering if anyone has made an external psu for this tt? Im in the UK so the motor is a 240v item. Any ideas?

Look for info on Linn LP12 psu's. I Think Linn and Thorens use the same or similar motors. I've repaired a Valhalla psu that I plan on trying with my TD150 Mk II. There's info on a Naim Armageddon clone somewhere on the net aswell.

Hi,
my TD150 had a 110v motor in it.
It was near stalling at 90vAC and would not start with 85vAC.
Your later models may be different.
I think the Linn uses a low voltage motor.

Hi. I have a TD145 MkII (electro-mechanically identical to any 160, except for the clumsy auto stop arm). I had been thinking on replacing the whole motor assembly with a PC floppy drive motor (beign a veteran Macintosh user, I think PeeCees should be useful for something... ).
I had been followingthis thread:
New EASY DIY brushless motor
or try
http://www.audioorigami.co.uk/FloppyDIYMotor.htm
also may I suggest
http://www.theanalogdept.com
which is user510 ´s site devoted to Thorens TTables
Hope it will be of your interest

I think Linn, Thorens, Rega, Dual motors are all low voltage (90-110v), they only have different series resistor depent on input voltage.

The Linn and most other turntables use the same 24 pole synchronous motor originally designed by Philips. The two windings are in series when used for 240V and parallel when used for 120V.

The Valhalla outputs 85-90v but this can be easily adjusted for a few extra volts. It is very easy to build a Valhalla clone using the HV discrete opamp and improvising with a different oscillator.

Thanks for the replies guys.

My only concern with dropping the volts down to 110v (and allowing the use of a geddon clone etc) is that in the instruction manual it mentions that the pulley needs changing??

You don't need to change the pulley. RPM is frequency dependent not voltage dependent. There is a dropdown resistor in front of the motor anyway, I don't think it runs on much over 110v anyway.

Good point! I'll have a read on the dvm tonight, thanks for that.
