Servicing turntables (1210s)

So... What's involved with servicing them?

Of late I've had to do a few repairs and have found myself taking apart nearly the entire deck. I'm pretty confident changing things out (tone arm, s bend, pitch etc)..

What would be involved with servicing one of the units? Just curious if there's anything I can do to improve the condition of one if I came across one for a bargain.

Cheers,

Cheers woody,

Need to try and find out where I can that lube or appropriate lube of some kind.

Apply lube everywhere. And lots of it. Come on, you know this stuff, Nelly.

Well that seems to be a company that specialises in servicing, not actually telling you how to do it.

I have the official Technics Service Manual at home in PDF - if anyone wants it, just PM me with your email address and I get it over to you when I get a chance.

btw nelly, you need a few different lubes, for instance the center pin bearings use a light "oil" type lube, and the for the tone arm spindles I used a teflon based grease (actually one for road and mountain bikes from a company called Finish Line) as even when it eventually dries, the teflon keeps it running smooth forever.

You'll also need ammeter/ohmeter (or mulitmeter) if you want to do the full service thing and make sure the calibration is all good.

Search your feelings and you will know the answer.

Sorry only saw this now..

Cheers for the heads up about the lubes. Have a multimeter just need to read what i need to do with it now along with the calibration etc.

Is your service manual similar to this one?

CLICK ME

Thanks for the direction. Keen on messing about a bit more on getting it back in perfect condition. Ever since finishing my Xoxbox I've had a lot more confidence in DIY electrical fixes etc.

Thanks again.

Feelings will hopefully eventually guide me in the way of the better lubes.

Which multimeter?

Any that can can do milliamps, resistance in ohms to at least .1 integers and volts. Probably any multimeter will do it.

@nelly - yes that is the book I have.

If you want detailed instructions on maintenance and mods then go to:

http://technics.junglist.pl/

Scroll down a little. The only thing I don't like about this one is they rely on the strobe rather than the multimeter reading on the control pot, but i suppose it will get you very damn close and as long as you match the two tables it's not critical to have them exactly calibrated.

If you want the really in depth guide:

You kind sir are a legend. Thanks a million for those links. Plenty of reading for me to do now!! ha!

Actually quick side question for you. I was fixing one of the S bend tone arms on one of mine the other day. Everything went fine and the deck plays perfectly. I am however getting a little ground feedback whenever I though the weight on the headshell. Or the screws that hold the cartridge in place. Nothing that would make me want to tear the whole thing apart but is it pretty much just down to the earth needing to be rewired or is it normal to get a little feedback when touching the metal parts on the headshell ?

Cheers

No mate, it's not normal, but before you reqire the ground which is a pain, just check and clean all the connections for the headshell; clean out the bushing contacts when you unscrew the headshell with a qtip and some alcohol based cleaner (switch cleaning fluid). Now clean all the little conductors for wires that connect the stylus body to the headshell conductor bushings. Finally, check that little screw(s) under the tone arm collar - once they were causing the problem. If that doesn't solve it then, I'm afraid it's time to open it up, and post back here if you need to do that and I'll give instructions on how to problem solve it, hopefully without having to pull a whole new ground wire.

Cheers,

I know how to remove the whole tone arm assembly so no problems there. Will go through cleaning all the terminals and checking the little screws again. Hopefully I won't have to redo the whole arm. Just wondering how I can check to see that the ground connection (if i do open it up again) is a solid one... Or will I have to close everything up turn it on and see whether there's still a small bit of hum. ugh..
