I tried to create an 8000 "system" near Portland, Oregon, USA by connecting a pair of Beolab 8000 speakers to my existing Beogram 8000 turntable and Beomaster 8000 receiver. The sound was great for a couple minutes before "POP", smoke and no more sound from the Beomaster 8000.

Did I permanently KILL the Beomaster 8000? If not, where can it be repaired?
If I repair the BM, can/should the speakers be connected to the headphone jack instead of to either pair of the 2-pin speaker outs?
If I substitute a less powerful Beomaster 24000 into the system, again, can I connect the speakers to the 2-pin outs or to the headphone jack?

Running the power output of Beomaster 8000 to the input of another amplifier (Beolab 8000 is an active speaker) could easily destroy both. How did you connect it? Martin

I made custom cables: 2-pin din at the Beomaster end and RCA at the speaker end.

Alas. See above. The 2- or 3-pin DIN outputs arexxx were speaker-level (amplified) outputs. The RCA inputs of the Beolabs are line-level inputs. Get a portable music player (rather than running the Beomaster in a broken state) and wire up a headphone jack to RCAs, to see if the Beolabs are still functioning. They have an automatic power-up circuit when they hear sound on the RCAs.

Dave: Two places to get your BM8000 repaired: https://atlantic-systems.com/ https://www.esc-website.net/Services.html Once upon a time, I believe B&O did have a special cable for connecting the output of an amplifier to a low level input. It was called a "z-coupler" or something like that. Maybe Steve at Sounds Heavenly can make something for you. I'm not sure things will sound all that great, although I have never tried. The BM8000 was never designed to drive active speakers. Derek

Derek thanks for your suggestions! My Beomaster 8000 is VERY heavy and I live near Portland, Oregon. Is there a repair shop in the Pacific Northwest?

Dave: Those are the guys that know vintage B&O well, especially Paul over at Atlantic Systems. I'd send it him, but call first. Just pack it really well with lots and lots of foam and styrofoam sheets to line the inside of the box. Then double box. I couldn't find anyone here in California. L&M Electronics in SF knew B&O, but closed several years ago. I tried Pyramid Audio in Austin, TX, but I didn't have a great experience with them. Derek

Glitch, Sorry, but my skills are not high enough to attempt dis-assembling the Beomaster8000.
