I recently acquired a Beogram 4000, well 2 actually, from which I have assembled one, that is working and with a working cartridge as wellJ

1) On the newer version a trimmer was soldered to the back of the main PCB (#4), just above the lower suspension pendulum. Does anyone know what this is for? Should it perhaps be removed?

2) Apparently there were different versions of the Beogram 4000, albeit with the same type number. Slightly different motor, different servo mechanism and there were also different pickup arms. One of the arms could simply slide on because it had an internal socket that of course matched the plug sitting on the base. The other had wires coming from the pickup fitting and these would need soldering to the base. Which of these is the new version and would the newer version be same that was fitted on the Beogram 4002?

3) Was the early version of the Beogram 4002, which was fitted with an AC motor, also fitted with the same quite heavy platter as the Beogram 4000?

Best regards

Hi Henrik,

               I am in the process of repairing a BG4000 with the help of another broken deck.So I'll try and answer your questions.

1) The trimmer or pottentiometer may be to adj the brightness of the lamp below the diaphram in the servo section and therefore the sensitivity of the servo.

2) The pick up arm with soldered wires was a modified type over the slide on(earlier version) type.I guess for better connectivity!.When replacing the latter arm for earlier type the counterbalance must also be replaced.I'm currently doing this,but not completed.

The sve manual for the BG4000 is on site if your a member and all this info is on it.A vey good sve manual!

Regards

Peter
