This is a great turntable. I have had mine for many years and am very pleased with it. I took mine back out of retirement a few months ago and found that things weren't working so well. However, I carefully removed the main gear/cam, removed the dried grease (from the bushing) with a q-tip and alcohol and lubricated with WD-40. I lubed a few other spots with WD-40, as well. Now, all is well again with this dear classic from the '70s. Grease was never a good idea with these old turntables. All they ever need is a shot of very-light oil now and then.

A faulty Zero 100 SB
I got a 100 SB recently. It looks very new and good, even the mechanism inside. However, there is a big problems I cannot get it solved. The tone arm is being 'kick' back half a mm after singing about 10 turns and it won't continue to move inward. Just repeating at that same position. I have tried on different locations on the LP and it still the same. I had adjusted the weights and everything it seems that there is a problem with the arm itself.
Will a tonearm be faulty?
Anyone has that experience before?
Many thanks for your advices in advance.
best wishes

Just about to start
My neighbour gave me his Garrard Zero 100 s last week as he was about to put it in the bin
I took it in plugged it into my system to have a listen to find it does not work!
Huge amount of hum from the unit and the table wont turn when the arm lifts ups
So I have just printed off the above dowloads and will start to look at and work on it this week
Will keep you posted as to my progress
Up and Running
Well
When I had a look it was really simple to resolve
The Unit had not been earthed properly, once done Hum gone!
Then some of the switches and springs had come off, so again once put right we were cooking on gas
however, it was fiddley and frustrating for a good 3hrs
Now it is working I need a decent cartridge and stylus
any suggestions?
Zero 100
Hi,
At last i finished serious working on my Zero 100 to get it (almost) playing like a new one...
The only thing i can't get working correctly is the automatic, everytime it's playing it does it well, only at the end of the record instead the arm is returning to his base, it started again...
I lubricated and cleaned everything, so what is doing this?
Also i found a small yellow wire at the end of the arm and on the inside. Can't find any information on it.It's similar with the cartridge-wiring, only it's cut.
I have another 100 for parts and ther is the same yellow wire...and also cut...
If someone has any suggestions? Thanks in advance.
Regards,
Ernst
Yellow Wire.
It's the tonearm earth. It should be connectedto a boss at the end of the tonearm and also the earth(ground) plate where the RCA's are.
As for the Auto Cycling. Under the Platter is an assy on the right side near the tonearm. Make sure that moves freely. If not it'll cycle continuously. It may be frozen in place. A soldering iron held to the bushing for a couple minutes will heat up enough to free it. Then clean and lube with Sewing machine oil.

Selecting Record Speed
I am having trouble turning my speed/size selector. It feels stuck and won't turn, any thoughts on how to fix this?
Thanks,
Speed
It should be somewhat stiff to maintain the setting, but fairly easy to move.
Carefully take apart the selector assy, clean and lubricate. Use Sewing Machine Oil for bearings and white lithium grease for sliding connections that would be lubed.

Garrard zero 92
I just downloaded the zero 100 service manual hope it helps me. I just finally hooked the '92 up to my amp and it contributes a loud hum to one of the channels. Pretty sure it's not the amp. I spose no one has a '92 service manual.
" I'll be back!!"
zero 92
yes, I have it. send me your email address and I will email it to you. I have about all the Garrard serivce manuals.
garrard '0' 92
Sure! Thank you!
I see from a cursory glance at a service manual that my hum may be result of a open ground line,
but why just one channel? Also, those cartridge wires are the smallest, thinnest wires I hope I ever have to attempt to solder.
wish me luck!
P.S. Thank you in advance for the manual!

12" record lowering in 7" location on platter
How do I adjust the dropping point for the arm on the record? I have the dial set to 33 rpm 12", and it is dropping too far inside this point close to the 7 or 10 inch setting.
tonearm position
i am having the same problem and can't find a answer any place. if you find the solution someplace, would you mind forwarding it to me. thanks
Selection cam.
Flip over the turntable. Look at the speed/size selector. There will be a rod on a plate just above the rotating assy. Follow the Rod to the tonearm. the rod attaches to a cam'ed plate that allows different settings. If it doesn't rotate freely, you'll get either 10" or 7" when 12" is selected. Clean the pivot and assemble. ONE DROP of sewing Machine oil on the pivot. Make sure it rotates back and forth FREELY!!! You should now be able to select 12" and get it.

I pulled my old turntable out of retirement and want to get it serviced in the Chicago area. Any reccomendations? It needs some TLC and I want to get it back into working condition. Thanks, Tom
Price for ZERO 100SB
What is a fair price for a ZERO 100 SB? It looks to be in VG condition, has a solid base (not plastic). I did get a slight hum when I picked up tone arm. Grounding problem? The guy is asking $125, but I felt like that was pricey....
Thanks for the manual!
Also about to try to reset the arm..
Thanks!
Thanks!
Garrard Zero 100S
I'm the (proud) owner of a Garrard Zero 100 S
(that's a real nightmare to set the arm correctly), it sounds really good and I thank the Vynil Engine...
