Power supply replacement for Thorens 190-1

[roker147]

Hi,

I recently stumbled upon a 190-1 at a junk shop and I'm in the process of restoring it. I'm going to go the inexpensive route for right now just to make sure it functions properly.

I'm purchasing an inexpensive Pyle Phono pre-amp and I'm buying a Shure M97xE High-Performance Magnetic Phono Cartridge to replace the OMB 10 (stylus is missing from it).

But my problem is I'm not sure where to get a 15 v adapter. There are plenty on the internet but they all between 40w-70w and say for laptops.

I actually tried these two:





used them very briefly just to see if the platter would spin and it did!

But I'm not sure that using 12v is a good idea.

Here's what the Thorens data sheet for the 190-1 says:


100-240 AC
1,5 W power requirement
15 v AC
50/60 hz

Any help would be appreciated, thanks.

Most 12v adapters that I have come across actually put out a higher voltage, that might drop under load.You can check the actual voltage with a multimeter.
Those you have can deliver more current than your turntable will use, so will hardly drop at all.
If it works for you, use it. You will not burn out a motor by feeding it a lower voltage than it is designed to handle.

Cheers,

I've been looking at universal adapters all day but I have no idea if a higher Watt output will kill it. Many universal adapters can do a multitude of different voltages, but most seemed designed for laptops so they output between 40-70 W.

But yeah, I suppose if 12v was working for me, that I could run it like that if it doesn't hurt anything.

Thanks!

The wattage rating of a wallwart is how much current you can draw from it without it burning up. The actual current output is determined by what is connected. If your turntable draws 750 milliamps, the supply that can deliver 2 or 4 times that will not get hot. It will not push that rated current through your motor.
