Thorens TD-520, any value?

Which power supply do you need? The external one is generic and simply supplies 16VAC to the internal one. The internal one is the complex/expensive one but I have a NOS one somewhere in the shop.

And it sold for $1000-$1500 recently, used.

OK. Thorens technical data says 17-19 but I've run it on 16VAC. You can probably buy this, try it, and if it doesn't work, use the connector for an off-the-shelf PS.

It's a simple job for anyone with some audio/electronics experience. BTW, if you find a technician to do it, I have the schematics for it.

If it says: "Umin 18V AC / Imax 250mA, 50/60 HZ," all you need is a wall-wart transformer that can output 18V AC at a minimum of 250mA. You can buy such from Radio Shack or any of a number of mail-order houses like Mouser or PartsExpress. However, considering your professed ignorance, the problem will be getting the right connector set up.

BTW, the Thorens likes more than 250mA, if available.
