Apocalypse Now?—Technics sp10 problem s

I’d been enjoying my Technics sp-10 mkii for a couple of months now but recently it’s sending out signs of giving up the ghost.

When I first bought it, the start/stop function was halting in the sense that I would have to push the button several times in order for it to perform the function. Independently of that, I bought bearing grease and after adding some drops, the halting start/stop problem more or less disappeared. Great.

But then the strobe light went out. It still comes on occasionally but it’s intermittent. Unless that’s a sign of deeper ailments though, I could care less about that.

Worse: if I play a record now after first turning on the TT, the speed is obviously haywire. One symptom is that the gear mechanism is clearly audible in the form of an unusual and grating grinding sound. Playing records when it’s like this is of course out of the question. The good news is that, for now, if I let the motor spin by itself (without the cartridge on) for about 10 minutes or so, the issue goes away. That is, the speed is dead on for the remainder of the listening session (I played it for almost 8 hours yesterday with no problems), and the grinding noise is gone. The bad news is that all this may be just a sign of an impending apocalyptic failure.

So, I'd like to deal with the issue before it gets to that stage. Can someone suggest the cause? Or better: the cure. Or, alternatively, and best of all since I’m not handy enough to actually fix anything complex, can anyone suggest a reputable service shop where I could bring it? I live in Los Angeles. I’m hesitant to ship it because I don’t have the motor clamp for shipping. For all I know, that may be the original cause since the seller shipped mine without the clamp. I guess I could have a clamp fabricated if that’s my only choice.

It’s a wonderful TT and would hate for it to die so soon in our journey together. Final question: if there’s a repair shop, should I go ahead and replace capacitors, etc..? What are people’s opinions on that?

Thanks.

I wouldn't mind running it constantly, but that won't solve the underlying problem the cause of which I don't know. I don't dare mess with the electronics as my ignorance would do more harm than good.

Corrosion death? Say it ain't so.

Calm. What it is: after old stuff gets old, sometimes it starts to act up. USUALLY this is because the old stuff that matters, like little circuit boards that control speed, stuff like switchs, get corrosion, the get tarnish, the get dirty. This is not a fatal thing, it just means the turntablle doesn't start right, the speed is funky. maybe the capacitors need replacing. With a little TLC your table will be good for another 30 years.
You need to find someone who can check over the electronics in the turnetable.

This is a legendary table. I don't know anything about it, except that there are forums dedicated to this turntable. Google it's model number and see what comes up. You live in a major metropolitan area,and I'm sure that someone on one of those forums will be able to help you find a qualified service tech in the greater L.A. area who can repair and or refurbish your baby.

I have one of these decks. If it were me I would treat it like my car and get it checked out - don't wait for the problem to get worse.

Put out an area location in LA on this thread and you will have members provide you with reliable contacts.

Whether you have a tune up due or a major repair it is worth fixing. An SP10 is very hard to find and/or replace. If for some reason you dont want to repair it you can sell it in no time here in "as is" or repaired condition.

Its worth fixing and worth more at that point if it has been updated.

Did you know the history on it when you bought it - was it used in a broadcast studio or in a private sound room?

Good luck

These are wonderful turntables and should be repaired. I had one before I found a MkIII. It sounds like the brake may need adjusting and the switches could use some tuner cleaner. The power supply could be in need of some new caps also. Be very careful using any kind of grease only use the recommended bearing oil if anything. There are many forums here for modding and repairing these.
