BSR C123R problem - UK Vintage Radio Repair and Restoration Discussion Forum

Hi.

I have a BSR C123R deck that is not working properly. The autochange spindle is snagging on the linkage under the deck. I have seen elsewhere that this may be due to the platter having been forced round. How can I return the platter to its correct position?

Thanks

The spindle, when in the correct position, should have the gap in the lower part pointing towards the back, right hand side of the deck. If it is already in that position, something else is causing the problem. If it has been forced out of position, you'll need to remove the turntable, insert the spindle into the centre post, then grip the centre post with mole grips and turn it to the correct position. Wrap the centre post with plenty of masking tape first, or you'll mark it with the grips, then the turntable won't run smoothly. If it is loose, you may have to fix it in place from underneath the deck with Araldite.

Thanks for the reply.

Do I need to remove the platter from the record player?

If so how do I do that?

Thanks

AS Audio1950 has said, the platter (Turntable) does need to be removed. It is held in place by a circlip around the centre post. The clip may be covered by a small trim disc, which is removable by carefully prising it off.

Hi

I have had another look at the deck the . The circlip has already been removed, but I can not get the platter to lift up, I don't want to break it by being too heavy handed, any advice?
When the turntable is spinning the centre post and spindle spin with the platter is this supposed to happen?

Thanks

Sounds like the platter is seized to the bearing hub and the whole lot is rotating when you rotate the platter.

If that's the case then you might be able to remove the platter by applying some releasing/penetrating fluid between the hub and the platter and some heat with a hair dryer while somehow stopping the hub from rotating when when trying to free the platter.

Hi

I have got the platter free from the hub without lifting the platter by gripping the hub with molegrips and spinning up the turntable. All is now ok and running well.

Thanks for the help
