Default Thorens TD 320 Power Supply

I just got a TD 320 with no wall wart. I have been unable to find a stick replacement on the internet. I was wondering if anyone knows the specs on this item. AC or DC, Voltage, amperage?
Thanks

14VAC. Any wallwart will do but better is usually better.

The wall wart (ac adaptor) looks like this from follow URL:
http://i.ebayimg.com/00/s/MTIwMFgxNjAw/z/2lEAAOSwBLlVewz1/$_3.JPG
I have measured all voltages under the different modes (wall voltage was 233VAC).
1) off-mode: 18V6AC (same value also at disconnect AC plug)
2) ON, stop-mode: 18V0AC and 22V8DC behind rectifier
3) ON, play-mode: 16V5AC and 19V2DC behind rectifier (across the main capacitor 1000uF, 35V).
Now a question: For the motor control Unit No 214753 (PCB No 6 646 056) of the second version (Thorens TD320 MKII) I am looking for the schematic. This is different from the schematic of the first version - go to

I need it to find out the reason for a burnt resistor, which is connected between the GND for motor control and the signal GND - go to

and

Who can upload the wanted schematic diagram ?
And what ist the actually aim of this resistor, which is not present at TD320' first version
Thank you very much.
