Greetings to all: I have a Beomaster 8000 and a Beogram 8002. I have been using an MMC-4 cartridge. I have tried to upgrade with an MMC-2 cartridge. I have tried two different MMC-2 cartridges at different weight levels. No luck. Once, one of them worked, but when I tried to adjust the weight level, I couldn't get the MMC-2 cartridge to work a second time. I am not sure what the problem is. Is it possible to use the MMC-2 with the Beogram 8002? Anyone else have a problem similar to this? I would be grateful for any information you might have. Best wishes, Donald
