I'm pleased with the purchase of this turntable. It had a couple of problems so I didn't pay much, and it sounds as good or better than my regular TT. I wonder if there is a service manual available? It seems in need of attention for being slow to start up when cold. Speed adjustment is maxed out, but is getting proper speed. Tone arm return is "sometimes". And I could use a tip on how to re-instal the spring in the cover and not stress the delicate plastic hinge I reattached on the arm side. Any help is appreciated.
Thanks,
Steve
Congrats with your turntable.
There is a service manual available on this site if you become a silver member
About the dust cover:
Do you mean that the plastic part of the dust cover itself had broke off - and have you glued it somehow..? If so, I'm afraid that no glue will stand the stress of the spring when properly installed. The 'contact face' is simply too small to glue properly.I guess you know that you'll have to twist the spring when mounting the dustcover. But the pressure will break the hinge, if it's only glued.(I've tried it once). But maybe someone has a good advice how to repair the part properly...
I think I'll try my luck with cleaning and lubrication inside to help the speed and auto return. Dillen mentioned an eccentric underneath in another post that I think could apply in this case, too. I'm a better at mechanics than electronics.
Yes, a delicate situation when the hinge in question snaps off. But I wouldn't have it it it didn't bust.
I decided to try acrylic solvent instead of glue. The same very thin stuff that I had used to fabricate a turntable dust cover. I carefully positioned and secured the hinge just right with tape and wood, then let the solvent wick into the cracks. Then I kept applying it. Messy, but it's hidden somewhat. So far so good, but I can see how strong that sprig is. I thought there may be a method or sequence to re-instal it that wouldn't be obvious, and would be gentle.
I have it attached without the spring for the time being, and I hold it up with a wooden stick. The Flintstones meets futuristic minimalist elegance. It does what a cover is supposed to, and looks good when it's just sitting there.
Thanks for your info and advice,
steve

Steve please tell us, what is this Solvent (Trade name) and could you tell us if it works with the spring attached, and pics if you can. If it works its a great solution
Collecting Vintage B&O is not a hobby, its a lifestyle.
Hi Soren,
It's called acrylic cement. The brand I had on hand was from Tap Plastics, a retail store. I'm reading that acrylic cements, generally are methylene chloride, primarily. I found some others on Ebay. I'm finding stuff about acetone dissolving plexiglass/,acrylic too. The stuff I got is probably a combination of things to give the desired timing for "setting up" when assembling sheets of plastic with the dissolving method.
I dripped some on a hidden part of the dust cover of the B&O and it responded by softening, so I went ahead and tried it. I can't recommend it, yet, because I haven't stressed it much. I'll practice gluing a junk dust cover and see how it really performs with a destructive test. Maybe I'll make sure I'm good and sober and attempt to get it assembled again with the long spring and some grease.
