I was looking at the service manual for where I might start looking regarding the suggestion by Telecine. I assume that it is an issube that relates to the tacho control. I do have a spare board that is not working that I could canabalize parts from if someone has an idea where that I might start replacing with what parts. I don't have a scope so

I haven't found a new motor yet so I tore down the faulty motor and tried to clean and lubricate it one more time and put it back together. This table was working fine except for the motor. For some odd reason the motor ran backwards this time and then blew a fuse. I took the motor apart and reassembled it and put it back into the turntable and

Well, I decided to try the easy thing and switch the platter motor with one that I was sure was a good one before trying different control panels or PC boards again. After several several hours of consistent playing with no problems, I began to suspect it was the platter motor. I put the other motor back in and the problem started up again which confirmed

Hello Soren, Thanks for your reply. Based on Martin's suggestion that it could be a dirty or a bad potentiometer in the control panel I switched out the panel with another I have and I swapped the PC board below it based on your suggestion with a board from my salvage table. The relay I am assuming is RL1 and is the clear plastic box with a wire

Thanks for the reply Martin, So I take it the servo motor is not a suspect. Could you point me to right direction to look for where the relay contacts can be found? John

I have a Beogram 4002 that is all working properly except that the speed which the platter is turning, slows down and speeds up on occasion after playing fine for 15 minutes or so. Sometimes it will correct itself but other times seems to stay at the same slower speed. I have put on new belts, replaced the capacitors, switched out the R15 adjustable

Yes again my thanks to the help of all of you. Olly has a good memory that I had 3 non-functioning tables to begin with, and one had to give up its life for the other two. I now have a second one almost working but am dealing with issues with a platter motor I believe that is not stable. It had the central pole stuck and needed to be taken apart to

As a final note to all of you who helped with the restoration and trouble shooting of this turntable I wanted you to know that there is now another fully functioning Beogram 4002 turntable out there in the world. Jacque was correct that I needed to tear down the table to get at the lifting arm to fix that problem. It turns out that the lifting arm was

Hello Jacques, I was looking for screws on the side of the assembly and did not realize that it was the top two to the left of the sensor arm, so I think I have got that now. Regarding a circlip tool, I will probably need to get that from an online source since Boise, Idaho does not have that many options. Can someone reccomend a source or a specification

Hello Jacques, I am afraid my friend you are correct, but I do fear this teardown. You supplied an exploded view of the tone arm/sensor assembly earlier in a post, can you tell me where I need to start first, it is the lifting arm (part 220) that is the problem I think. Should I remove the adjustment bushing (part 236 in the manual) on the right side
