RIP Dual CS 620 Q.

Why don't you try being a little more helpful rather than always being the aimless critic?



And PureQuill, that tech is not deserving of the name Doug. :D

Doug

Yes, I would like to learn about this better way to make a Steuerpimpel.
Good Doug/ Bad Doug! Know the difference! LOL!
Actually he is a great tech I just don't think fully auto Duals are his specialty.
 
I fix the steuerpimpel in a similar way as in the photo, it's not crappy for me.
The difference is that I take the mantle of a coax antenne cable. Why? Because it works.
And some guess work here: it might hold longer than Dual's original part. I've never seen a Dual turntable that made it with the pimpel intact in this millennium.
 
I hate to say it, but that's a crappy home-made fix.
There are much better and proper ways to fix the lift issue, and worthy of those fine old platter-spinners.

I myself bought one from a vendor for around 12 bucks plus shipping. Was it worth it? I don't know. Now is it an original replacement or something the vendor determined met or exceeded the original part? It's a turntable. I wonder if Dual actually had a part manufactured or found something off the sewing machine assembly line next door that would work? We will never know. But if the shoe fits...... :yes:
 
@ wrbear so does the aftermarket replacement do the job?
And was it very hard to do yourself?

Yes and no. It was for a Dual 1216. It was shipped in a baggy with 2 other rubber parts for a restore. So, were they original Dual parts? Who knows...I'm happy with my purchase but...I wouldn't knock a DIY is what I'm thinking. They make sense and have a proven track record from what I can see online. I could have saved money with a DIY but I wanted an added umpf so that I didn't have to take it apart again in my lifetime.

Oh yea what would be the better fix, I have fixed more than one using something like this.
 
Hmmm, to be honest, considering that some of the original pimple types (there were several over time) weren't all too robust, I'd say: Better a good diy solution than one of the originals that give up all too soon.

The trouble with Monycat's "fix" is in it's design - as I see it, the hollow "sleeve" and the mentioned of use of ball point pen sleeves simply cannot function the same way as the original pimpl design.

Maybe THIS can explain things better.....

This is a non- critical part of the mechanism. all it has to do is: be of the correct hight, give some grip, and don't prevent slip.
And it's a reversable fix. No damage at all done.

If the piece of plastic used to replace the original is of the same height then it will allow the lift pin to move as intended.

I have fixed 3 different Duals just recently my CS 731Q using this "inferior" fix and all are operating as designed.

So again what is your solution as these are no longer available.
 
One must always offer a solution/fix to a problem instead of a critic to someone else solution, also, it's not very constructive.

I think that all of the rubber parts for Dual turntables are unobtainium. The rubber has deteriorated due to a time factor even for original replacement parts that are marked Dual. The part I bought online was a DIY replacement for the original part which was closer in composition and size to the original. That’s about it. That written, I would have to write that any option to fix this is fair game and only to be proven good or bad in time. So far I haven’t seen a post saying “the BIC pen option has failed”.

Who knew this would be controversial? :confused:

All I know is, this works. I have done it on 5 or 6 tables already without issue. Will it last 30 years or even 10? I don't know but my best guess is it will last a very long time. Dual didn't know how long their rubber or plastic pieces would last either.

Regarding fears for the Yamaha PX-3: Picked ups a PX-3 andhad it checked and serviced at a very reputable shop in Berkley, CA . The unit's working condition was checked for operation and settings, cleaned and lubricated were recommended and tested for 4 hours. The tech reported the unit in excellent working condition. He did advised that when there are problems it is most likely the tone arm. He could not confirm if problem was cause by poor operation or maintenance. The PX-3 tone arms can be reasonably repaired by a competent tech. From all the info I found this is a great tt.
 
Thanks to all you folks who had constructive suggestions. I have had numerous Dual turntables over the years, from the late 60's to just a couple of years ago. They all developed problems in the changer or arm return mechanisms. I really liked them but unfortunately had to give them up. I now have a better understanding of ways to get them going again thanks to you.

Oh, but it IS a critical part!
The adjustments of the cueing height etc. depend on the proper part(s) installed.
Homebrew fixes and guessing are at best as good as winning the lottery.

OK, you're correct and all these other people are lying about their repaired turntables working.

I see.

Ok so your avatar makes it clear you are no amateur..

You have explained why the home brew fixes are not to your standards & inferior to OEM parts which are no longer available.

So please share your correct to spec critical fix.
I am sure that many here would love an alternative to home brew.
So how does one properly replace/ fabricate this critical component?

If you don’t have a better solution then please just say so.
