Discussion
My dad has an old turntable from a Toshiba seperates system from the 80's. The main unit died a year ago but the turntable still works.
We were thinking about using it to convert records to DVD's.
The unit used to plug into the main hi-fi unit using a 3.5mm jack plug as the power source, and a label at the back of the turntable states "9 Volt 50ma".
On removing the jack plug power supply, there is a white and red wire and it has metal sheathing round the edge of the two wires.
Should this literally be as simple as positive, negative and possibly the shrouding as an earth? I am not getting much result testing as such...

Unless there is a fine speed adjustment and a strobe light, you probably need to put 9V AC into the inlet.We were thinking about using it to convert records to DVD's.

When these turntables are not fine speed adjustable they usually have synchronous motors.
Don't forget also, that you'll probably need a phono preamp, since few modern hi-fi's have a phono input on them.
A computer sound card might be able to pick up the signal directly, but you'll need the RIAA (frequency) correction, and the soundcard won't do that.
I made mine, a few years back, and I think it cost me £5 all in. You can buy them for about £15.
Also, the red and white wires could be anything, but usually red and white signify left and right audio!

Like I say, you probably need to put 9V AC in there.
Typically you would simply use a transformer from 240V to 9V, without a rectifier or a regulator. Most small power supplies are rectified and regulated. They produce DC.

I will open up the back later to check the motor arrangement.

As above, I'd be tempted to buy a USB turntable - by the time you've faffed with the existing turntable (and possibly had to buy a new cartridge/stylus), somewhere between £40 and £60 could sort the conversion out far more easily......

How many albums do you need to convert?

Well if you're putting 9V DC in and it says DC, the motor must have a problem. That or the speed controller is a gonner.
Possibly - it is almost as old as me, and has been sitting for a long time 
My, get this, c a s s e t t e d e c k, is not quite as old as I am, but I still love it.
In it's time it was a nice machine. It's got light touch buttons, and inside massive solenoids to operate the transport. Push the light touch button, and there's a huge CLUNK, as the thing comes to life.
Proper equipment!
I still do mix-tapes, and I still prefer doing them on tape. I just find it easier to edit, than faffing around with the mouse. I actually do quite a bit with the the computer too. I buy single songs on Amazon or whatever, and then record them onto tape so I can listen in the car!
I don't know what I'll do when I cant get a tape player for the car any more.

I have happy memories of spending a few quid on high position chrome and metal blank tapes and frowning apon those 'normal' position, rough sounding efforts.No treble! At all! I don't know what I'll do when I cant get a tape player for the car any more.
It's funny how things have advanced and how much we take for granted now.I now walk out to the car with a tiny 8 gig USB stick, (which is about the same size as a stamp and weighs less) and can store several hundred tracks - all of which take seconds to put on.Compare this to my Dad and Grandad, running a fairly successful disco back in the 70's and having to cart hundreds of records around with record decks etc in a van.
