I have an 8002. I am looking for a shope that will tune it up, rewire with better cables and fit a new cartridge. My e-mail is robert2303@yahoo.com. Any help is appreciated.

again, you are cracking me up...

this 8002 should be straightforward...

though not always true, my experience w/ b&o -and a lot of other things -is that if the piece is in excellent cosmetic condition that it more than likely was well cared for when it was in the previous owner's hands. its current status is most likely not from abuse, but rather just age (e.g. caps) or that it may have suffered a surge. that is why i gambled on this one. even if it rendered useless -it is at least in excellent cosmetic condition...

btw, i too have have been a patron of dillen in the past (caps and lights for a bm2400) that i re-did inc'ing a nos case -it is magnificent (but that is another thread). well, the 8002 should be here next week -the last piece for my 6000/8004 setup.

now i may have to up the bm6000 to an 8000!!!

projects... they keep me out of the bar!

Are you on drugs?

I think it's great to hear that there is now hope for many turntables in that we now have a qualified repairer in the states, something we've been waiting for for ages !

Thumbs up for the good work, Phil !

I hope your experiences w/8002 give you EVERY opportunity to reap the great rewards that mine has given me: increased humility, introspection, belief there must be a higher power, interational relations, a glimmering awareness of things electric, polishing tecnique, etc. I expect it will. God works in strange ways (let me state, I'm an atheist-actually I became a Zen-Atheist while working on the TT. Everything is everything, the ZA mantra)But the God metaphor just makes sense-believe me, if you don't get it now, you will later!

The LED display should illuminate the decimal point when plugged in. If it lights, then the 5vdc section of the supply is probably OK and the 300uA (800uA/220v units) fast fuse inside the transformer case is defenitely OK (how'm I doing Dillen? Oh yeah-did I forget to mention that here you will get expert coaching by REAL technical experts; Dillen has been my mentor-I expect he'll check in) If it doesen't, the simplest first step is to give up.Just kidding! Simplest first step would be pull the transformer and check the internal fuse & quick check of secondaries w/AC voltmeter. Do you have a manual? you can download one here if you are a silver or gold member, or you can download for free @www.vinylengine.com. If I never touched your machine, I doubt that either fuse is blown. Part of my development has been becoming aware that when fuses blow there is a cause, and it is me. (I blew my transformer fuse checking the secondary voltages-quite simple really) But, especially with Dillen and others tutelage, whatever the problem is, it will be quite discoverable and correctable (did I mention Faith?)

I am also awaiting TT#3, which I bought on ebay for $71, to see if it's sensible to fix it or use it for spares. Dillens cap-kit arrived by post today for TT#2. Life is good Phil

just sourced an 8002 (not here yet) defined as having "no power."

it appeared to be otherwise excellent and the price was right, so...

anyway, stumbled upon this thread in "presearch" before its arrival. that *r*ction comment cracks me up... enough that i followed phil's other threads...

sorry to hear about the spot damage mr. bozzo! were you able to salvage the cover?

btw, the link to your site was interesting -you sound like a neat fellow to know!

at any rate, i am sure i'll be back here when i start troubleshooting the 8002 in earnest. sounds like i may start in the power supply / transformer area looking for bad solders, anything else?

take care,

Great to hear that you've rescued one more of these nice decks.

We have some filters blocking posts containing certain words or phrases, I believe your post(s) went pass a moderator because it contains the word ere*tion.

Third time's a charm!

#4: We're wiser and happier now!! Happly to report that 8000 CPU "can" works nicely in 8002. (8000 CPU in 8002 "can": NG for sure, tried that too). Played music all afternoon on #1 8002 with no spontaneous erection of tonearm! Kudos to Dillen and Auric for their support on and off this board, thankyou. Capacitor kit ordered for #2 8002. Incidently, I bid $30 on a damaged 8002 on ebay that needs a cover hinge, cartridge and keyboard. I bet I can fix it with my spare parts left over from an 8000 a friend gave me in pieces. An 8002 w/MMC 1 went to $705 today on ebay and it's reseve wasn't met! If anybody needs 8000 parts, let me know. I guess my trusty TX is available now, as well as a MMC20CL that looks nearly new and is in original box. I also have a radial arm TT (2000?) w/o cartridge free to anyone who can pick it up (northern NJ, USA) Thanks, Phil

I am happy and wiser! Installed the 8000 "can" in the 8002 and all is well! Spent this afternoon enjoying music thru #1 8002 with #2s MMC 1 cartridge-marvelous, and no spontaneous erections of the tonearm. Cap kit #2 ordered for TT#2, aand I bid $30 on a beat-up 8002 on ebay that has broken cover and pushbuttons, no cartridge, but case is good looking. I bet I have enough parts/smarts to fix it cheap if I get it. I'm motivated-an 8002 w/MMC 1 failed to sell @$705 today because his reserve wasn't met! I've got 3 turntables and four cartidges. Anybody want a good TX? I also have most of an 8000 that was given to me in boxes (needed tacho whl). I've robbed the base and processor can, and the transformer and cartridge were missing. I also have a fairly new MMC 20CL if anybody's interested. Also a radial arm (2000?) w/out cartridge is free for the taking if anyone wants it (I'm in northern NJ, USA)

Kudos to Dillen and Auric for their most helful support both on this forum and off.

We are wiser and happy! I swapped the processor "can" from my parts 8000 into the 8002 and everything works great. My only concern is that I didn't replace the capacitor in the 8000 can-it went into the now unused 8002 can. I played music on the 8002 for several hours this afternoon with no spontaneus erections (of the tonearm). Thanks to all of you for your help, kudos to Auric and Dillen!

Paranthetically-most of the 8000 parts are available if anyone's interested. A friend gave it to me in pieces-it needed a tacho disc. However, I've swapped the base onto my 8002 because it was mint. The transformer and tonearm cover are missing as well as many small parts.

I also have very nice looking MMC 20CL in box. Phil

Derek,

I never tried that either but since the processsor is basically the same, only the code differs, I suppose it wouldn't hurt anything to try. However, if it doesn't work we still aren't any wiser.

Martin:

I was told by a B&O technician from B&O of America that it is possible to swap the entire microprocessor module and that the units will work.

Obviously the software "features" of the 8000 would then be transferred to the 8002, however the units will work.

I will qualify this by saying that I've never performed the swap. Just what was conveyed to me.

The processor is unique for the Beogram 8002 in that
the programmed code in the processor differs from that
of a Beogram 6006/8000.

The good thing is that the B&O part numbers are stamped on the CPU's, Phil needs a processor with the number 8340454 on it.
