Great point about E-clips. I get more confusion from people asking for the wrong part and complaining when they get what they literally asked for. Sometimes even suppliers are confused and back and forth ensues, even though the package clearly says what it is. Slang conquers all.
i bought a Dual 704 in 1978 it was a great sounding turntable in the day the only thing i hated about it was that plastic head shell mount so i filled it with Blue Tack to increase the mass and it sounded better, even when i bought a Rega Planer 3 and my present AR Legend with Linn arm i still kept the 704 but 10 years ago my step son wanted a turntable so i gave him the 704 but he moved to Norway and i think he gave it away that's life i suppose, i was a massive fan of Focus their first 2 albums where fantastic, In and Out of Focus & Moving Waves are well worth a listen to
Ooow i like the direct drive system, smooth and no fluctuations unless the control board has nasty capacitors. I've always called them circlips but e-clips and c-clips are a better discription :-). I liked your drifting off into madness, me and my frends are much the same lol. You are not the only person that's a bit mad, in a good way of cause :-D
That is a DUAL made turntable? i always thought Dual was the bees knees in audio equipment! I have a Yamaha Direct Drive, not used it in years as everything is in the shed after moving. i hope I don't have to repair it as it looks like a solid lump of wood except for the holes drilled to put thing into. I have not tried to get the turntable off, but it looks as if it is part of the motor itself. I couldn't see how it came appart, but I wasn't trying as it is still working. But I have this brain that wants to know things, so was just going to have a quick peek, if you know what I mean? Anyway, I just started watching your videos just before the Covid virus hit and have found them interesting as this was the sort of things I used to do at the Man Cave bench. So keep the videos coming and I will keep watching :-))
Could denatured alcohol work in place of Isopropyl Alcohol, in these hard times? It is clean enough to use as a fuel and is available in the paint department at Walmart. I have not been able to find the 97 - 99% Isopropyl Alcohol in over a month.
You should have cut the innner wire spike or folded it flat against the innner wire at 21:14 that is a short waiting to happen. apart from that a great video enjoyed watching it, keep tham comming.
Thanks for this. I need to do a service on my 604, which has the same cue lever problem -- well, the height is good but the action very slow. Also am going to replace the Rifa safety cap which I hear is prone to fail. I'm pretty sure my 604 has tone arm return at end of record too, surprised the 704 does not. Perhaps a problem there in yours?
Question: my 704 makes a zooming sound. My old Dual does'nt do that because I can connect it with an ground (earth) wire to my amp. How can I get it stop zooming? Do I need to build a wire in the 704? Thanks allready
I have a dual CS 620 that uses EDS 910 direct drive motor with a broken control board that's beyond repair. The motor appears to work but no matter what signal I give it cannot be controlled. Tried using PWM with Arduino but nothing seems to work as it speeds up beyond 78rpm.
I have one that I want to buy that the arm doesn't want to stay up... or so they say. Everything works but the arm won't stay up, could there be something that is gummed up and sticking?
FOCUS, long forgotten, their main hit was Silvia if I remember correctly. They were not around here for very long, if I remember they were Dutch or German, I an just to lazy to see if I still have the record as it will be in the shed. Had to dump thousands of records when I moved, there was just no room in this crap modern house! I've seen bigger hen houses! Everything is buried in the shed and no doubt getting broken!
Hi Dave, oldbean, again. DG records with the Tulips, are much sort after. I am a Digital Man, and a Bird Lover. So only interested in who is the pianist playing the Chopin?
Some people are idiots trying to fix stuff that they have no clue how they work, And even worse when they don't know that they don't know like the owner of this turntable.
Just curious - Why didn't you lubricate the motor bearings while you had it open? I'm going to rebuild my Sony PS-X75 turntable. I've purchased some expensive silicone grease for mechanical surfaces. I'll have to re-cap the PS because I've heard that the voltage can go up if that's not done. That in turn can blow the computer chip, which is not available anywhere. There are very sensitive coils in the Biotracer arm. Have you ever worked on one? If so, are there other things I should know? I read that one person was able to replace the control system with a Teensy++ 2.0, which runs at 5V. It took LOTS of programming.
@@12voltvids I don't remember seeing it in your video, but I could be mistaken. It's my guess that you have to take the motor apart to clean and lubricate it. Since I'm a little nervous about doing that, I wanted to see someone else do it before I try. I wasn't being critical of your repair.
My mother's turntable only turns when you press the 33/45 switch, and then only about an inch. I think it could be a problem with a leaf switch, but I am going to have to bring it to my house so I can keep diagnosing it and referring to the internet.
No matter the clip, we always called them Jesus clips, because when you take them off, they like to go flying, and you always go "Jesus where did that thing fly off to?"
Looks like something my father would do to repair the wire lol, him and electricity didn't go together, he was a bit of a liability! I hate trying to solder that wires, you have to be quick as it shrinks back if you ain't quick enough. Oh the poor stylus !!!!!
In Europe we call them Circlip's or C Clips. Another name was a Jesus clip. I don't know why. Perhaps it's because if they snapped or fell off people cried out Jesus.
I found that covering the clip with a dab of lithium grease helps keep it from flying away when you're trying to put it back on. It'll stick to the surface even if your pliers/screwdriver/finger slips off.
hey mate great job! I have a dual 704 which works great 95% of the time however every so often when I move the arm over towards the record to play it sometimes shuts off? This only happens sometimes but I was wondering if this is a big fix? cheers
I’m having the same issue, everything seems to cut out straight after moving the tone arm in , I’ve been finally trying to get my inherited 704 that’s been in storage for decades into shape so I can move it on, I’ve replaced the strobe and reoiled and cleaned some of the mechanism. But I’m going to try this method on this video today to see if that helps. It’s something to do with the timing of the switch and I’m hoping it’s an easy fix! If it works, I’ll let you know.
Seems that E clip would be more appropriate. Other than WD-40, which is pretty useless BTW, the Mopar Rust Penetrating lubricant is one of the best (Crysler-Dodge). We also use some products from Crown, firm known for car rustproofing. Ever since they started to use Calcium Chloride on roads working with rusted parts that break became mechanics nightmare, you need to torch everything these days to get it loose without braking, eg. yesterdays K-frame on little over 10yr old Accord. So, yes it is worth rustproofing if done well. Chopin Piano Concerto on DG, really I love CDs and digital media. No thicks, pops, compression, no no bass and all the problems that go with Emil Berliner invention, still way better than the drum by Edison.
Mitsubishi made the Eclipse back in the 80's and 90's. I had the GSX AWD which could smoke mustangs at the time with a simple boost controller. Now back to your regular programming ....
you weren't TRYING to be funny, you WERE funny, loved the scissors by the way i must make one, looks very handy. oh and you could let your cat out after the bird ; )
Why not get one of these. www.the8bitguy.com/product/retro-grooves-vol-3-vinyl-record/ I'm sure they wouldn't mind using it. I've seen a few TH-camrs using this music.
A Dual with dried up grease. That's new... not. I do more Duals than any other brand when it comes to gummed up mechanisms. Duals were meant to be serviced regularly, but most people had no clue. Forty or fifty years later, these things are beyond due.
If you are fussy about the pitch control you would be jumping out of your chair every few minutes, as the speed changes as the record plays. How many youngsters would know what a record is these days?
You are fantastic Rick. My Dual 1229 is dead in the water here in Toronto and it needs totally taken apart cleaned and lubed and reassembled
Gotta love that wiring job the guy did.
1 like for the E-clip.
one of the best Duals
Very helpful vid ! Thanks a lot !

Excellent explanation how to repair the 704 turntable. I had the exact same problem und was abble to fix it. Thanks !!!
Awesome video! Havnt check in on the channel in awhile!

The jokes were eclipsed by the e-clip. Lol. Cool repair, it's great it's a relatively easy fix. Compared to what it could be.
Eclipse is also an IDE for Java programming. :)

Well I "would like to be like you" . A good fix, another one gets to "carry on" !
Thanks tons
Mike thank you for this great video. How do you change cables on the 704 ?
Could denatured alcohol work in place of Isopropyl Alcohol, in these hard times?
It is clean enough to use as a fuel and is available in the paint department at Walmart. I have not been able to find the 97 - 99% Isopropyl Alcohol in over a month.

There's a return spring that's probably lost it's mojo. I was surprised also the 704 doesn't return like the 604.
I sure do’t your skill to do such a Geary job. Keep dual shows going please

Classic..
Brake cleaner works fine too from auto parts store.
Just be careful not to put it on rubber parts. But the same is true for WD40 as well.
Wow, guess it is summer there with birdies chirping wish you could fix my Duals on TH-cam
I see u are I BC I hope you are in good . To hell with all who trash your awesome work. No one in Ontario fixes Duals

Dutch.
I have the same model bought new .The tone arm doesn't drop down when I drop it with the cueing arm. Any suggestions with that ?
Needs the old grease cleaned out
Hi Dave, oldbean, again. DG records with the Tulips, are much sort after. I am a Digital Man, and a Bird Lover. So only interested in who is the pianist playing the Chopin?
After adjusting the tracking force, did you set the anti-skating dial? Have you ever worked on a CS 721 turntable?
Yes the anti skate was set to same as tone arm weight.

@@davidhilton342 how did it go ?
@@danielvandergriend9724 I had to bend that little copper/brass thing near the motor to prevent the automatic shut off. That fixed it. :)

what did you spray on the cartridge contacts? Thx
I don't remember. Either nutrol or deoxit.
It's really Over-Engineered, a recipe for disaster! In Europe we call them Circlips!
i call them jesus clips loos one and ya go jeeeeesus where did it go
Mitsubishi made the Eclipse back in the 80's and 90's. I had the GSX AWD which could smoke mustangs at the time with a simple boost controller. Now back to your regular programming ....
You should check out the Red Demon GSX on TH-cam. Currently the fastest stick shift drag car in the US.
Never remove e-clips unless you have extras. They tend to go flying.
Then they are called a jesus clip.
I ended up using throttle body cleaner on a cotton swab.
Don't you need to add new grease?
I did, mollykote.
Lube it with Motorkote hyper lube. The lube will never dry up
you weren't TRYING to be funny, you WERE funny, loved the scissors by the way i must make one, looks very handy. oh and you could let your cat out after the bird ; )
I'm funny as in funny ha ha or funny?
That's a quite btw. Now why said it and where.
@@12voltvids funny ha ha. YA made me laugh anyway. When you were talking about the eclipse and e-clips.😊

What if it was the motor you can’t get those any more ?
A motor like this should never fail. There is nothing in it to fail. The control board could though.
12voltvids thanks for your videos
I have a 704 and the motor started needing help to get it rotating...hoping to find out if it can and how to lube motor
I buy clear heat shrink to show off my soldering skills. I have nothing to be ashamed of and I'm sure you don't either.
shopper drugmart has alcohol in ontario sorry might have some there
I like focus..another underrated band..but not by me..
A Dual with dried up grease. That's new... not. I do more Duals than any other brand when it comes to gummed up mechanisms. Duals were meant to be serviced regularly, but most people had no clue. Forty or fifty years later, these things are beyond due.
I did hundreds of em. And bsr and garrard
Can these dual 704 motors be regressed?
Regreased
Did you replace the C clips? lol jk hahaha
No threw them away. Extra parts.
So your repairing one of these th-cam.com/video/HoPXQ9fotZM/w-d-xo.html
Would love to follow these postings, but can not stand the untidy, annoying clutter. CLEAN BENCH.

If you are fussy about the pitch control you would be jumping out of your chair every few minutes, as the speed changes as the record plays. How many youngsters would know what a record is these days?
Oh, nooooooo!!!! Just replace the cable instead of soldering them together....
Why put in the extra cost? This is a perfect repair :-)
