Dual 1009

Back in 1974 I bought a PE turntable and it quit working in 1994. I didnt Know how to repair it and there weren't any AudioKarma sight nor a repair shop that would fix it so it just got tossed in the dumpster with the other trash. On saturday I found a 1009 Dual and won the bidding on that auction sight. Hopefully it will arrive intact as it is suppose to be in good working order. Can anyone here give me some info on this model and what to be on the lookout for. It felt like a little part of me died when I tossed the old PE and am hopeful the 1009 will fill that void. Probably in that era many good duals and PE were just thrown away.

The 1009 is an idler drive fully automatic TT. The idler itself gets a bit harder with age and slips. That causes slippage between the motor shaft and the inner surface of the platter and speed is drifting or below normal. If the startup time is a few secs then it's an indication of slippage.

Another thing to look at is the grease in the gears that form the automation. In general, it needs to be cleaned throughout an new grease applied.

Also, it's a good idea to drop a drop of machine oil in the platter shaft.

Another issue with this TT is the headshell. It's a really obscure design with a quarter turn screw securing it in place. If this is broken or lost it's really hard to find a replacement. And the headshell contacts need to be thoroughly cleaned with alcohol or metal polish (really gently) as with age oxidation takes its toll.

Although the 1009 is one of the first "low tonearm mass" TTs around '64, it isn't really low mass by modern standards so it doesn't work well with high compliance carts. I should think that a moving coil cart would be fine. High compliance carts combined with the floating chasis don't do well, especially when the TT is put on a less than rigid desk or on wooden floor.

I also have a 1009 and when I find the time and space I will go through it and restore it and mount an Ortofon MC10 cart to it.

Just reading through these tips you have posted. Could I expect to find some of these same issues with a Dual 1002F that I am working with?
 
You got me here. I don't know. I don't even recall if there was a 1002 model. I need to look that up.
 
Yup!

I would second the motion. These Duals were built in the 60's. Hard to believe they are "middle aged" When I get one the old dry grease gets removed and regreased. The center gets a drop of oil. Most need to have the motor taken apart,cleaned and oiled. The ilder wheel usually gets a light sanding as money is a little scarce around here. Most times its enough to get the auto cycle to work. Decided to run only Duals as most models are similar making it easier to correct problems.

Good luck.

I really like the 1009. It was the first in a series. They lacked a cue and a antiskate but they sound great. My first one was originally bought for parts. It turned out to be too good to junk. Fixed the tonearm so the headshell worked. Put on a Shure M55 and wow. I have had 4 or 5. Gave one to a friend last week. He wanted to stack LPs and 45s Paid dearly for that one as it came with tall spindles both LP and 45s. He used to the old Voice of Music tables that had an arm to balance the stack of records. Never had seen a Dual spindle.I also gave him the German base which is much nicer than the United Audio base. I have not had problems with this models headshell. Even the broken 1009s arm was easy to fix. The later 1009F,1009SK and 1019 headshells are a pain in the donkey as they like to cut out. My 1009SK does it. Some of these are worse than others. I always hold my breath when I crank up the 1009SK.

As said, a good cleaning is in order. Most of the time the motors need to be taken apart,cleaned and oiled. The grease underneath should be removed and regreased. Loads of posts here on that. Do that and your 1009 will givw you years of service. Enjoy!

Thanks for your input. I just downloaded the sk service manual. the instruction manual was in German from vinylengine. Is there a download anywhere else in English?
 
Vinyl engine shows two service manuals for the 1009, I believe, one German (de) and one English (en). It could be that the English one is a German one with an English translation of the text added to the end of it. Did you scroll all the way to the end of the document?
 
I do not recommend a moving coil. The designers of the 1009 did not design the shielding of the arm and the tonearm wiring to handle signals that small.

Use a cartridge like a Stanton 680EEE designed for a tonearm of early-seventies vintage.

Thank you all for working with me on this. The turntable which hasn't arrived yet is equiped with a shure M73ped cartridge. the fellow who is the seller said it would probably need a new stylus. I've been looking for one but haven't found one yet. Another thing that is worrying me is I don't think there is a changer spindle with it and are they very hard to find?
 
also , where is the best place to buy a stylus for this. I saw it mentioned somewhere that a M75 stylus would work on that M73ped cartridge.
