Hello,

 

I recently posted that I had replaced all the capacitors and fixed several problems related to my BG 8000 which I thought all was resolved. I unfortunately did not play a record all the way through to the end. What happens now when I do play the record is that the tone arm picks up 2 tracks before the record is finished playing. Anyone have experience with this happening and what the fix is?

The other thing that I found out is that if there is not a record on the platter the arm will go to the 45 rpm 7inch position and just stop and sit above the spinning platter without returning to stop.

The Beogram will reset (go to park position and standby) if no opto pulses has been sensed for a
certain amount of time. If the needle breaks or the record is damaged and jumping track etc.

When it stops and just hovers, take off the servo motor belt and see if the servo motor tries to
move the carriage further left.
Clean the optos at the end of the threaded shaft.
Check for obstructions in the carriage path. Sometimes, the friction sticker from the lid mech (an apprx 1x1½ inch
opaque plastic piece) falls down and gets in the way around this spot. A stray cartridge protector can also cause this.
Finally, clean and lubricate the threaded shaft and the two steel tracks.

It will also go into park and standby if very fast pulses (lead out groove) are sensed after a certain
amount of normal pulses has been counted (after a certain position about 75% into the record).
Check with another record if this one has abnormal inter-track grooving.

Hello Martin,

Thanks fort he reply and help. I opened it up and found that there was something obstructing the movement. The front rail the arm slides on had not been snapped in place last time I put it back together and had come loose. All is well now.
