A challenge to DIY electricians

Rescued turntable ( record player) how to power
I've just rescued my JVC turntable from the roof space on a whim to play old LPs.
It was part of a HiFi unit which has long since gone, together with hand books!!!
At the rear of the unit there are 3 wires, red & white plugs which I asume are phono connections & also a small black & silver (female) plug & info DC 11-13V
It is similar to the connectors on chargers for drills & torches etc.

How will I get power to the unit & if I can will it work through a cinema surround sound amplifier?

does it say what amps or watts it requires ?

You should be able to buy a plug in PSU (Power Supply Unit) at 12volt DC provided it can cope with the load of the turntable, which I wouldn't expect to be a lot, so it shouldn't be a problem

this would probably do, as it's a regulated power supply.

You will need to check the supply polarity, and back of appliance.
The power consumption will be important

a turntable needs a dedicated "phono" INPUT" on any amplifier you cannot plug it into a standard input a phono input has a built in internal pre amp.If your amp does not have a phono input you can buy an add on unit that enables a standard input on your amp to be used like this one

Hi, thanks for help so far!!!
1/ The only info on back is a sticker which states Input 11-13v followed by 2 short lines one over the other , the top oe solid & the other in dashes.There is also a diagram which I believe is showing the "polarity?" a circle with plus sign going to the centre and a circle with minus sign connected to the outer
2/I have looked @ Maplins
http://www.maplin.co.uk/Module.aspx?ModuleNo=5439&&source=14&doy=3m12
& the connector is similar these, 2.1 & 2.5 plugs. How do I tell whether mine is which of these? The dimensions given on the 2.5 seem to match mine except the outer diamete on mine is nearer 6.5mm
As it happens I have a variable variable adaptor with 4 different connectors & so I presume all I need is a converter plug.

At the end of the day I guess really I'd best go to a local electrical warehouse with my bits to see what they can offer!!!
Thanks again,,TonyB

if you are not happy doing it yourself, take the whole thing to your local branch of Mapins, radio shack or similar

The 2 lines above each other indicate a DC supply
It is important to get the polarity correct yours has the centre pin as positive so you must get a power supply that outputs positive on the centre pin although some you can switch the polarity on to the centre or outer pin.

All this still only gets the turntable powered up but as I mentioned in my previous post if you do not have a dedicated PHONO in put on your amplifier then you will need to buy an adaptor

Hiu all, I got in touch with JVC who bless them actually replied. Feather in their cap.
However the connector was designed specifically for the HiFi unit alone & as the set up was discontinued before 1989 no hope for spares!!!
I suppose I could do some cutting & soldering with a different plug but at end of day decided to settle for a new turntable & £50 quid (alot less hassle)

Anyway thanks again all
