Hello everyone. My Beogram 8000 turntable will not start and operate properly after setting for a few days with out multiple attempts and much fiddling. I searched the forum and found this to be a common complaint. Replacing the electrolytic caps seems to be the typical fix. 

I have removed three electrolytic caps from the main circuit card and I've opened up the sheet metal encased processor board. It looks like it contains a cap in a flat planform near the center of that board. I can't locate that one on the drawing and I can't see values marked on the case. I think I remember reading in another post (that I can't find today) that this cap should be replaced too.  Or perhaps first.  

Please, if anyone can tell me the values and perhaps a source of supply for the one with the odd flat planform, that would be appreciated. I intend to replace the others with Panasonic caps of the same values from Mouser. I have read of a capacitor kit here. Information on that would be helpful too.

Or maybe I'm all wrong about that. I see its marked 1.970. I bet that device is a 1.97 MHz crystal. I see it on the drawing now.

So, I guess my question now is simply: is there any electrolytic caps I should replace on that board. C28 perhaps. 47uf, but what voltage?  Can't read it. 

There are also a pair of 22/66 and a pair of 22/40 I could replace on that main board. Those too?

I'm not familiar with the BG 8000, but normally in a unit of this age I would change all electrolytic caps.

There is a manual onsire for silver and gold member, in there there is an electrical parts list, where the sizes and voltages are listed, just skimming through there I see some 15-20 pcs. As for the voltages, get one step higher as in the list, like, 16V- 25V, 63V-100V.

Or send a mail to member Dillen on this forum, he may be able to supply a cap kit.

I second Soren's suggestion to contact Martin, who goes by Dillen as well. I have restored two BG 8000 turntables to working condition and one BG 4002  thanks to his capacitor kits. He sends a clear schematic for the capacitor placement. Then there is no guess work involved as to the capacitors placement and their values.
