Trying to salvage a Dual CS1249

Postby jlydic » 18 May 2017 21:29

Just got the word that my local stereo repair shop can't salvage my Dual CS1249 turntable. Back in the day, my dad bought the stereo system while he was stationed in Germany with the Army. He gave everything to me after my parents split up because he had no real use for it.

A VE user on another part of the forum suggested I post here. What are the odds that the repair guy was blowing smoke and that this can actually be salvaged?

When I last tried using the system, I noticed that sound was only coming out of one channel. Also, the sound would eventually fade and disappear after a short while. I would have to disconnect then reconnect the AV cable to get the sound back.

If it can't be salvaged, I figure I'll probably try selling it for a few bucks to anyone who could use it for parts, then put the cash toward something new. But I'd hate to scrap a repairable vintage turntable, especially a Dual.

Thanks in advance for any advice!

Well,first guess is something is wrong with the cables,or some contacts are
corroded. Things like that happen on a machine from 1975. What cartridge is
on it. Maybe that is defective. Anyway,it doesnt sound like a case for the
thrash bin to me.
And i repaired and restored a 1249 myself some years ago.

Hi Jlydic,

If your machine is working mechanically and just has the issue which you describe here it should be a relative "piece of cake". If I had to guess I'd first look at the contacts on the sled on which the cartridge mounts to the head shell. Try to burnish them with a pencil eraser. Ultimately you may have to get an Ohmmeter and check the connections from the cartridge to the cable connecter pins.

Your "professional" audio technician should not be in the business. Is he the one who used to post here with his vast knowledge of physics?

Hi,
Since I just finished restoring a 1249, the pictorial of the work is now uploaded to my website, under Service Tips / Restoration 1249. There are three sets of pics. The first seventeen are from the dearing ring repair for repairing the lift ring (59) fails.
The next fifty or so are the fine tuning and calibration which is carried out similarly on each unit serviced. The last 180 or so pics are the actual restoration process.
If there are any questions arising from any of the restoration processes shown, don't hesitate to ask.
Regards,
k

Hi Jlydic.

It all depends on how hands on you want to get. It sounds like a cable, connector or cartridge problem to me. The AV cable connections can get dodgy but its a process of elimination

Your local repair guy doesnt sound up to much.

If you dont like diy work Im sure someone would be interested in it for restoration. Perhaps you could get it valued here and sell it to a Dual enthusiast. I dont know its value :)

I think it simply a case of whether you want to lovingly restore it or sell it on

All the best

I also had a Dual passed down from my father. It was not worth much but had sentimental vakue so I decided to have it restored by a Dual specialist. If you can DIY, great. If not, there are specialists out there that can do it for you depending on location. Luckily, in my area, (NYC) there are 2 I trust.

I would check out the RCA connectors at the amp end since sometimes they get damaged from years of flexing at a sharp angle or being pushed up against the wall at the back of an amp.

Also make sure there is no tarnish on the headshell pins and the contact strip of the tonearm, as well as no tarnish on the cartridge pins or the connectors from the headshell to the cartridge.

You can check some things such as for an open wire or an open coil in a cartridge with an ohm meter.

Let's back up. WHY did the repair shop say it cannot be salvaged? They need to tell you in detail what is broken or missing. If there are missing parts and it worked fine except for the sound before you brought it in then I sure would be suspect. If anything is broken parts can be had if you know what they are and where to find them. I have recently seen a bunch of 1249 parts on ebay. Usually, they just need a steuerpimpel, lube and adjustment, not parts.
