Argh!!! Tech 1200 problem

Every now and then, my one 1200 TT will lose the right channel sound. I cant figure it out. The wires are not cut, they are still soddered in as far as I can see. Any help will be awesome. It even happens in the middle of mixes!! I got it to work by playing around with the tonearm base somehow. Thanks in advance.

check your needle. check all aspects of the cart, stylus, everything. this happened to me for a bit, and if you touch the headshell while playing, sometimes it would go back to both channels. damn annoying. get new needles if you have to

yep, check the needles. also take a pencil with a new eraser and use it to clean the contacts on the tonearm it self, inside the part that the carts fits into. also check to see if the carts wobble a bit when they're in the tone arm. if they do the you can use a jeweler's screwdriver (also known as a precission screwdriver) and tighten the screw on the tone arm near the cart. cheers.

Ok thanks =) I dont think its the needle because I switched it with my old one when only one channel was coming out and it did the same thing. I tightned the tone arm a bit and cleaned the contacts so I guess I will just have to see what happens. Thanks again

if you try everything you can think of and check every single part there is in the table, just take it to a repair shop hehe

sometimes thats the last thing you can do, but be prepared for a pretty big bill.. that shit is never cheap. good luck loki

have you plugged the turntable that cuts out into a different channel on the mixer to see if it's your mixer and not the turntable? this happened to me. it turned out that the left side of one of my channels went out but the right side would still play.

I had this problem.

For me the cause was the phono plug itself. Inside the plug, two connections have to be made. If one of these connections is missing then the sound cuts completely. I fixed it temporarily by slicing open the plastic outer casing (if you have the stock phono plugs on your techs, you should be able to slide the cover back to check) and resoldering the connections. It worked, but I've got shaky hands so my solder job didn't last long.

I eventually ended up just going to the shop and slamming down $30 to get completely new plugs.

Shiny. Gold. Plugs.

So if you can, see if you can slide back the covering on the phono plug to check the connection. It might have burnt off or snapped with age. I wouldn't suggest slicing it like I did, because that just made a huge mess.

Best of luck to ya. I know your pain.

I checked out the plugs to see if it was still together and it looks good. When it was out, I tried swithing the plugs around and it was just the left channel on the one table. It didnt work when I put it on other channel inputs. Im gonna mess around with it more when it breaks again but for now its working...guess all I can do is wait. Thanks again for the responses fellas.

Oh, razzi, I love that quote from Hackers. I usually have it as my signature too =)

before you hack anything open get some isopropyl alcohol
highest alcohol cntent you can find k?

now get a Q tip, get it wet, ram it INSIDE the hole and 'prod' the contacts. the alcohol will clean teh grime, and evaporate(its a good cleaner, do not drink)

thats should do it!
