Vtg BSR turntable directions or hint wtd

[mongoose1983]

I know this is no 1st world type of Q, but if you can help me, please do. It happened last week I helped cleaning the house of a colleague that is moving out of town. She let me had many things, I even got me a couple of beautiful parrots! One of the things I got was a very nice late 70's old Korean Stereo "Silk Sound" brand. The 3-on-1 type featured a really nice BSR record changer on top. Well I fixed the stereo, but since I have my Hi-Fi stack in here I thought about just keeping the SRB record changer. It works very good and I plan to construct a base for it. I already have a Technics here but it is letting me down on speed, so I am in need of a turntable and I have no $$ to spend so that's actually why I am asking.

THING IS... I would like to know what is the polarity so I can directly connect it to 120v and use it as a single piece of equipment. You see there is four leads, black-red-brown-red. I need to know what's the positive and negative so I can go ahead with my purpose.

Pictures below. And thanks in advance to anybody able to help me with this!

You all have a good weekend!

Black -
Red +

The other two could be switch signal though, so just 120 thru black/red might not do anything

If that doesn't work a mate of mine used to work in electrical repairs so I'll check with him

Thanks! I'll join the UK Hi-Fi forum and hopefully I'll get the record player working alright with my stack in here
