This is what I have going on. AC power cord in the L-, L+, R+, R- terminals, with thing ground wire in G. Don't know why it's soldered in there.

Sorry, wrong photo.
And a close-up of where the {what would be] phono cables taped into a power cord.
What is the black object the red arrow is pointing at?
That's the power cord in the field of vision that was spliced onto the phono cables. I tied it up later for the zoom out photo.
Next issue is you need to find out where the power cord is actually connected to the TT motor...
I take it it's from the 16v supply, which then ends up as green+black wire into the connector on the circuit board labeled 'B'...then the output to the motor from the four cables, blue red and black. I took the motor out to oil. No adapter came with the TT, I was considering a pro-ject speedbox to supply the 16v out.
Question, what is the black clip in the top left of the circuit board that holds the metal plate on the underside of the tonearm assembly (labeled D105 D109)?
I have a TD160, so I'm not familiar with any outboard PSU for a Thorens TT. Sorry, I don't know what the clip is for.
Thank you, you've been a huge help. I think my order of operation will be as follows:
-solder on shielded wire to the RCA connections, install RCA females and ground
-16v power supply (after researching, about $30 for replacement adapter on the td147; I saw a pro-ject speedbox sell on ebay for $75 the other day, I might as well save up for that, especially since it has a 16v out)
-new cartridge (at under $90, either shure M97XE or a Grado)
I hope that will get me going, at least. I'll tweak the tonearm later. Any other suggestions on how to make this into a great table are welcome.
Nice photo. The AC cord is connected somewhere else.
Two phono audio cables and a ground wire are connected to the terminal strip shown in the photo, not the AC cord.
Please take a clear photo of all cables/cords coming out of the back of the turntable, shown together within one image.
Normally, except the cable was cut and then attached to a power cord (I will attach a close-up photo, where the electrical tape is). I tied the power cord together, but it definitely has taken the place of the phono cables. That white cable that is attached also with electrical tape connects to the G terminal.
I have no clue what was going on here. I hope nothing is damaged, but I don't see how a current could have gone through this.
If I were to remove this and attach the Canare, would I go about by resoldering the Canare wires to the terminals, instead of undoing the power cord splice and attaching wires there?
If the phono cables were cut and the wiring were attached to a power cord that was then plugged into an AC outlet, doing so certainly might have damaged the wiring and fried the phono cartridge if it was connected to the tonearm headshell at the time. If there was no phono cartridge connected to the tonearm as of then, you might be in luck as far as damage is concerned.
Bummer - very bizarre. How would I find out if the wires were possibly damaged? I was going to replace the cartridge, anyway, but I hope there is no other damage.
As for the Canare - should I simply resolder those onto the phono terminals?
Images I posted in this thread show the proper wiring scheme for the phono cables and ground wire.
