    If you probe at P76 before plugging it in and there is 5V then lose it on plugging it in then there must be a short there. You said earlier you changed out the microcomputer IC oscillators. Did you remove the microcomputer ICS when you did that? If so, did you make sure the oscillators were shorted while doing the procedure? It is too late to worry about now but in the future one shouldn't really mess with the oscillators unless there are symptoms there is a problem related to it. I do change

    Hi Alf, Don't try to tackle too many issues at once. Right now it appears your issues are related to the power supply circuits. You need to troubleshoot the relays and see why they are acting the way they are. Determine if the relays are good or if the circuit controlling them is faulty. If you think the voltage regulators are running hotter than expected then check what their incoming voltage levels are. I would go through the power coming in from the transformers through the rectifiers and

    Hi Alf, I would inspect the work that was done and continue testing the new unit then. Perhaps one of the startup relays have gone bad. I had to replace a couple before. John

    It is a good problem to have where your new Beomaster is in great cosmetic shape. That means another future restored Beomaster 8000 can go back into service. I never trust a non-restored Beomaster 8000. They are too old now. I wouldn't risk doing any further electrical damage to it until the capacitors have been replaced, the connections checked out and the power supplies verified. John

  • Re: Beogram 8002 Repair

    Hi, it does sound like a weight adjustment problem. First, you must have a cartridge attached. It sounds obvious but a lot of people try to initially test the a Beogram without a cartridge because they don't want to risk damage to an expensive cartridge if something goes wrong. That's a good idea but pickup an old, non-working cartridge cheap for that type of test. Second, if there is a cartridge on the tonearm and it still won't drop then check that the tracking force knob is present

    The artist is Felipe Pantone (Argentine-Spanish artist). I like his work and thought it looked good with Bang & Olufsen My particular piece is called " configurable ".

    [quote user="Dennis"] Looks great! If you had asked me when the art was from, I would have guessed the 1980s! [/quote] Haha...I agree. Maybe even the 70's ( Robin Trower's "For Earth Below" album cover comes to mind). Great designs though. There will always be places in somebody's home for Bang & Olufsen audio equipment from the 70's and 80's. The late 60's and the 90's weren't bad either. 70's and 80's are my favorite era's for

    Updated my Beosystem 8000 This year I updated the 7 segment displays on my Beocord 9000 and Beomaster 8000 inbetween projects for other Beosystem 8000 owners. In addition I changed out the artwork I had on the wall with my Beosystem. I kind of like the new look. The 1980 Bang & Olufsen design still goes great with art from 2019. I like it ... except for one stray speaker wire I should have tucked away in the SC80 cabinet. -sonavor
