- This was a 50 year service on this unit...
Really only few things went wrong in that time:
- It needed a new belt
- it needed a repair of a corroded PCB track (inside sensor arm)
- it needed adjustment of a bias for the first sensor amp transistor
- re-capping
- and a bit of lubrication to get rid of squealing during arm travel
- and maybe cleaning of limit switches
Great machine and if I ever wanted to get a turntable, it would be this or perhaps some other linear tracking unit like Revox or Sony (very rare).
For real help with it and upgrades, please contact Rudy at beolover.com
He also has a uTube channel of the same name and a blogspot.
He really worked it all out, has upgrades for replacing incandescent bulb with LED, remote control and other options.
Very helpful and knowledgeable guy.
Please share the belt placement?
Will do. Once I get some time to get to the sensing circuit repair. But in general, pull the platter up to remove it, clean the belt contact surfaces on both the platter and motor pulley and then install the new belt. The easiest way is to fit it around the platter while holding onto the belt (to keep it tensioned), hook the bit you're holding around the motor pulley and drop the platter into the bearing.
