Kenwood KD-2000

Just got this serviced and there's no way to stop the platter? I press the cut button and the tone arm lifts and returns to rest. But the platter keeps spinning, even when the "play" dial is in the off position. As long as it's plugged into a power source it keeps spinning, is there no way to stop the platter?!? It's very annoying!

sounds like they didnt wire it right when they serviced it. I have never heard of a platter that never stops so it sounds like who ever serviced did some thing.

Eather that or sounds like the tonearm switch (assuming its got one) is wonky.

Stupid question - what exactly is a "tonearm switch"?

i believe its a switch in the tone arm that when the tone arm goes in the cradle, the platter stops

ok, ben, i am going to apologize ahead of time for the completely useless answer that i can't resist giving:

>Any more ideas on how to get this damned thing to stop turning??<

unplug it?

ok, ok, i'm sorry. just flat stupid and unforgiveable. but i just couldn't let it go.

yes, tonearm switch is caput. get new one or wire in a manual on/off switch on a separate circuit.

Yeah, unplugging it helps (obviously), but I really don't want to have to plug it in and unplug it after every use. I'm still not sure I know what the tone-arm switch is, but I really don't feel like bringing this in again to be fixed so I guess I'm stuck unplugging it after each use. Oh well...

Did it do that before you took it into get serviced? if not if i was you i would take it back there and have them fix it right.

IMO (even though you didn't ask for it) as soon as you DO feel like it, have them fix it right regardless of whether it was that way before or not. Then next time you need a repair, go find another shop. Too many hacks out there. :mad:

They should have caught something that obvious the first time it was in.

Is there an easy way to fix the tone arm switch by myself? I really can't afford to pay for more servicing (they only gave me a two week period to make any claims and that's already up). Help!

Quickest fix is to plug it into a cheap outlet strip & turn the strip off.

And cross that repair shop off your list.

WOW!!!
The repair shop didn't check the unit before returning it to you? Great way to lose customers. I would bring it back and have them repair it the right way. Check it out completely before accepting it.
Does the TT have an on/off switch or does the tonearm movement control the deck?

I've made that mistake myself - let too much time go by before taking the unit back.

But in that case, I don't think it would have mattered. The "professional" repair guy would most likely have failed to find the problem the second time around as well. He apparently used some el-cheepo cleaner on my amplifier. I eventually found that all the "repair" required was a deeper, more thorough going over with DeOxit.

Of course, that shop is now off my list.

What's with some repair shops??? They take our prized possessions, charge a small fortune (or a large one) and screw the units up! I know that before I return a repaired unit to its owner, I make certain that it's in 100% working order. I don't want the unit to comeback for a simple oversight on my part.
A few words of advice. Have the repair shop check the "repaired" unit, in front of you, before accepting it. That will put them on the spot when/if something is not right.

There's no "on/off" switch, there's a "play" dial that you're supposed to turn and then the platter rotates. The problem is that even if the play dial is in the "off" position, the motor keeps going. And if the play dial is in the "on" position, pressing "cut" only lifts and returns the tone-arm to rest - the motor keeps going....

The play dial (switch) is either defective, wired incorrectly, or not connected. It may be that the wires for the switch are soldered together. If you can, open the TT and post some pictures of that switch.

One question. If you let the platter spin after pressing stop, does it stop at some point? There may be either a brake problem or if it uses a microprocessor, it may be defective. If the later is the case, you'll need the service manual for the individual waveforms and oscilloscope to read them.

Nope, it never stops (I've let it go for a few minutes thinking it would just slow down and eventually come to a stop). I'll try to get a peek inside but it's not exactly easy to open up...

One problem is that shops that do strictly "electronics repair" do not do any serious restoration. They meet the bare minimum requirements to "fix" something, and if it runs it's done. To these guys, an old stereo is no more a "prize possession" than a cheap old VCR or a blender. So if you're like most people out there who have a toy BPC stereo and don't pay that much attention to how good it sounds, that suits you fine. But folks like us need to seek out vintage restoration specialists. You can either do it by trial and error, or find somebody on the web (such as this site) to take or ship it to.

I still don't know of anybody in the entire city of Denver that is particularly good at restoration. The closest place I know of is Vintage Electronics down in Colorado Springs.

For now I've got it plugged into the "switched" outlet on the back of my receiver, so it only spins when the receiver is turned on. It's temporary, but a solution none-the-less...
