I replied on another thread about getting one of these recently.
The radio part is working fine now I have replaced 2 faulty valves.I'm not touching anything else on the radio part.
As for the turntable,the motor spins and the speed adjustment works,but the motor will only turn on if I move the tone arm away from the platter(ie to the right) not the other way around so it's currently unusable.
I had a look underneath the turntable and took the platter off and I can't work out how the switch is activated.
It looks all mechanical down there.Are there any adjustments or has something work out?
I am not game to touch it but would be fun to see the whole unit working.

Thanks in advance.

I think the record player is a single play unit, probably a BSR. To switch these on you have to move the arm to the right. If working properly it should automatically turn itself off at the end of play.

Do you have a model or type for the record player?

It's a BSR record player indeed. I moved the arm to the right and the motor turns on,but as soon as I place it toward the left if a record was on the platter,it turns off.

When I first started playing with it yesterday,the turntable was spinning with the arm in its resting position. I couldn't work out how to stop it,so I ended up turning the power off and unplugging the radio.

As I wasn't sure how it worked all I did was move the arm around without plugging any power to it,then removing the turntable from the box and having a look underneath and that where I am up to.

Andy, have you tried loading a record onto the spindle in the upper position and then swung the upper arm into position?
Then the player is ready to go and the start stop control will work in sequence.
If you just put a record on the platter, the mechanism thinks its finished and will be in shut down sequence.
We really need a photo of the changer to see what model it is and if its a single or auto changer.
Fred.

Perhaps sequence is indeed wrong. If you leave the stacking arm up & away from its run position that can cause issues.

I hate automatic changer turntables: Some of the designers should have been shot. That switching on method is common.

Also look at the "mechanics": By now most of the grease soap had gone hard, jamming parts. The only spec. I have ever seen is for Philips and that was for Shell Alvania 2, which may be superseded?. However, a heavy grease will cause drag. Do not forget the spindle: Some BSR platters will "bind" and hell & damnation will not get that platter to move.

I use a lot of "Shell" and there is evidence that the farm has used it pre 1926 when it was Bio Co. As noted before there are engines here into the early fifties still using it. Inox grease can be bought in small tubes in several grades.

Remove the old grease. Mixing grease soaps & brands is bad news: They can go solid.

I will try an old record tomorrow.

Not sure how to post photos.
Here is a link to my google drive.

Not sure if this is helpful.

Thanks.

EDIT: I have emailed photos for upload.

The original record player for this model is a single speed, single play type. The service manual has diagrams & instructions for the player.

It really matters little if it is a changer, or not, if it has an automatic return. It can loose adjustment and grease soap going solid is the enemy in all of them. They are supposed to be serviced around every 500Hrs: Never / rarely seems to happen.

It's not a changer.

You switch it on by pulling the arm fairly firmly to the right. That operates a switch which should latch on when the motor starts from memory. Sounds like that's not happening so yes, clean the old grease out of the fairly simple mechanism and apply some light oil. Careful, don't let any oil or grease get near the rubber jockey wheel, the inside rim of the platter or the motor's stepped pulley.

Agree with Marcc and Ian, where it is a one play the motor starts up by swinging the tone arm to the right.
That pushes the power switch on and a latch drops to wedge the switch on.
When the tone arm reaches the inner spiral on the record the return wheel is engaged and lifts the arm back to the rest point and trips the motor switch off.
Momentum then ensures the arm drops back onto the rest and the platter then runs to a stop free.
If any of the sliding arms/latches/friction clutches/ prodding bits/springs and glued up then the thing does not work.
What Ian et al says...…...clean it up and it will work.

Fred.

This model looks like it is actually a U63C with a 3-speed BSR Regent GU4 or GU4A player. The Regent players are very simple & reliable.

The U63A is single play 78RPM only. Models U63A, U63B & U63C are all identical appearance & electrical wise.

Yep! Looks so simple and yet anything causing binding like dry grease soap, dirt & corrosion, will bring it all to a grinding halt. I see rust & it could be both sides.

Looks like a simple fix; if the switch is OK?

After seeing the picture all I want to know is WHERE are the other 59 parts those things usually have!
There must be a bunch of clik clak parts hiding under the platter!
And they are all glued to gether.
There has got to be a friction disc thing that senses the record end angle and shuts the thing off, or, does it just run down the end spiral on the record going shoonk...shoonk...shoonk until some one lifts the arm?
Oh, that's how the older 78 things worked...………………um.
Looks like we are back to Marcc' observation that the 3 parts have a bit of rust'n'crap on them and the switch is not latching up to start with.
Fred.
