Dual repair: Dr. Dual or ???

Sorry, my computer has been iffy, so I haven't responded.

Remove the leads, put one lead on the + for that channel and the other on - for the same channel.

So one of the cables on the middle of the RCA and another on the inside? I'm not very good at following instructions, but if this what I'm supposed to do, I didn't get any reading.

Greetings, your turntable is close to 50 yrs old. The contacts on the headshell or sled has metal contacts pressed against plastic. Check to see if any or all have loosened with age. My 1010s uses the same sled. It had loosened with age. I used epoxy glue where the metal is connected to the plastic. A little dab will do. Let dry for 24 hours. Then, gently move the contacts out for better contact. Did this on the 1010 three years ago. No problems since. While at it, replace the RCA cables. The originals suck. If your meter has a contenuity check on it, use it to see if the wires in the arm are good to where the RCA connect underneath. After 50 yrs and sitting in a garage the wires may be bad. I had a 1219 where the wires rotted. Good luck.

The pins on mine were falling out, too! I did exactly that, and resoldered one of the wires that connect to the cartridge. I did change the RCAs; nothing. About rotten wires, the really small cables that connect to the tonearm underneath have a greenish tint to them. Could that be it?

If the turntable will be overhauled for that price, with a 1 year warranty, then go for it. If he's just going to fix the immediate problem you describe, then it's a rip-off.

The guy was probably a car salesman in a past life; trying to explain how "unknown" everything is, and wanted to replace parts "just in case." A little bit pushy...

Dual interconnects are notorious for going bad. I would replace those first and go from there.

On tip: when you clean the contacts in the headshell where the sled makes contact (the flat metal tabs), they may look clean to your eye. Snap a picture with your cell phone. Often times the camera will show black oxidation that your eye does not see. That helped me in the past.

The pins looked disgusting to just my eye, so the camera might not be pretty!

I am not knocking anyone for having someone else fix their Dual nor am I knocking those guys that fix them for others like the two gentlemen noted above. In fact one of those two guys gave me some advice via email that assisted me in doing a fix myself.

I was just trying to say that if money is important to you and you are at all inclined to fix stuff yourself that you might want to try it yourself.

ok, now I'm up to 4 cents

I'm getting better at soldering and such, so I might actually have a chance to fix it.

If those pins and the tabs they make contact with have oxidation, then you will not have good conductivity.

I used a Scotchbrite pad on the pins, both sets. Nothing.

Some kid,

I would check the continuity of the headshell wires. These wire have crimped connection to the contacts which can come loose. I had to solder two wires to the contacts. Using your multimeter to beep with continuity, touch one probe to wire where it connects to the cartridge and the other probe to the contact strip. Sort of a three handed operation but can be done.


I also had to glue the contacts down.



Doesn't show well, but the soldered connections are on the blue and white wires.

I found Dan's P.M. to me, dated August of 2015.
His post in today's thread concerning his Dual does not do justice to that message.
Shame on Dan for his wording of the post which casts doubt as to Bill's and my capabilities [and personalities].

$150 is not unreasonable if everything, and I mean everything, is done to it and the price includes a warranty.

A pencil eraser is the best thing I've used to clean Dual contacts.

Who's Dan?

 

[NoTransistors]

He is member 91r100gs. Post #19. I got his 1st name from his old P.M. in my files.

I can highly recommend the work from either Dr. Dual or @NoTransistors . Both do expert level work!
