Hello,
I have recently purchased 2 Gates radio company CB-77 turntables. I got them at a collage surplus for a dollar for the pair.
These are very heavy and have a good bearing in them a sfar as i can tell. Replace the plynth and it is basically what us diy guys are looking for.
Are these decks something that a person could convert to a HI-FI table. The motors are held in by rubber dampener, one deck all of these are broke the other they are ripping. The power swith has been disabled and replaced with relays for hook up to the radio station, i have not tersted them yet.
I was thinking of making a solid mdf base for then contoured around the equiptment (like a goldrin lenco upgrade) Dynomat the inside install a different power switch in the front, make a armboars support off to the right whitch would be replaceble and easily removable. and giving the unit a piano resin finish. Having the table set into the top a bit with either sorbothane between the top and base or other material not yet decided.
Let me know that you Guys think.
p.s. I still havent finished my complete diy table. It got cold and my friend with the lathe cant use it because it is in the shop snowed in.

pics?
Hi
Do you have any photos? Presumably they are heavy duty idler drives so should be candidates for the Garrard/Lenco plinth treatment. It sounds like you've got the ideas sorted more or less, motor mounts are all you need. At that price maybe folks figure you've been very lucky, dammit!! 🙂

The Gates are solid turntables. Quietness of drive depends on condition of the idler, of course. The on/off switch is a mercury switch, IIRC. Actually, I've got a couple in my garage awaiting rebuilds myself!
I have used these in a radio station setting, and setting them up properly takes a bit of adjustment. Somewhere, I have the docs for this table, but have been unable to locate them. I've always liked the styling.
There usually was a 1/2" foam rubber isolator running around the perimeter of the underside of the table. Kind of like door insulation. I'd have to check, but I think these were just placed in situ without bolting to the tabletop or plinth. I'll have to check, though.
If I locate the info at home, or somewhere on the net, I'll post it.

I beleive the switch was removed and replaced with a relay but i will take some pics and post them as soon as i can.
And any info would be great i think cleaned up and new plinth these would be good weird tables.

Gates CB77
Solid tables and a nice example of "broadcast art". I have access to some of the parts for the drive and speed select.
Only user for the Ashland motor used in the 12" CB77 and 16" CB500 was Gates. Treat them TLC!
I know of 2 sources here in the US that can rebuild the idler wheels/pucks.
Of all of the broadcast table, the Gates were the best. The later direct drive Technics tables were much quieter, but not an interesting to see.

I was very impresssed with the automotive shifter style speed select. I really want to build a plinth for these but now i am trying to finish my full duy table and i am almost done.
I had trouble finding pics of this table on line i would be intrested in seeing what the original arm looked like. Was the gray research tonearm a transcriptor arm?
