New Dual 510

Post by dagfinn » 31 Aug 2019 12:28

Hi all, here's the Dual 510 I've been waiting for :). My first Dual, so I know nothing much about it, except that many people likes it.

I cleaned off a little dust, mounted my test cart 2M Red, balanced arm, set VTF, set antiskating (interesting with one scale for conical, and one for elliptical). Speed seems fine. pitch control works. Plays just fine :). Auto off works, fantastic :).

Now, it looks in very good condition, but some service points are necessary, I guess. A new belt, perhaps some oil? It has 5-pin DIN, so rewire to RCA...

regards,
dagfinn

Good old deck and the 2M Red is but the beginning of your cartridge journey (it should sound amazing with a 2M Bronze stylus for example).

Belts from Thakker I think. Oil? the main bearing is lightly laden and not the same as for the autochanger based models. There may be enough oil left in there already, but once you've worked out how to remove the inner hub which may be locked into position by a screw held sliding plate (long time since I 'did' a 510) it seems good quality chainsaw oil may be what you need as it's viscous enough not to creep away from the bearing sleeves. I also remember 'Zoom-Spout' being recommended but forgive me - I don't know how runny it is or not for main turntable bearings although I'm sure it'll be fine for the thrust pad and point at the bottom. Sewing machine oil used to be the recommendation for motor bearings but getting to the top bearing in these Dual motors takes some care and maybe a coarse needle syringe as in a clock oiler.

Hi and thanks lbls1 & DSJR :). It looks very little used, very little dust under the platter asf. But I'll give it a quick check and oil (once I find which screw to loosen and find the sliding plate to lift off the platter ;) ). One thing I must fix is capacitors for power switch. Now it says "pop" when turning off, an indication that capacitors are ready to be replaced. So I've ordered some :). Soldering is a new, necessary skill I'm trying to aquire.

It already has a Sumiko Rainier instead of the Red ;).

... and I actually managed to fix the capacitor issue, thanks to information on this site. Replaced 2 capacitors, one for power and one for strobe. The strobe cap was the sinner, popping on on/off. So sweet with auto-off. Got some oil at the same time. Goodnight table ready :).

The Dual automatics are quite the joy when operating properly. They serve your records very quietly, have a strong and wide soundstage, and they perform this with a grand old style unlike most turntable makers; Very similar to Garrard but most distinguished even from them. You'll enjoy it.

Hi lbls1! You know, I feel the Duals are underrated. I know it reminded me of my moms Garrard, but it's not the same, really. For the moment I'm listening to Billie Holiday 1937-47 recordings, one of my few mono albums. Works perfectly.

I managed to get the autocue point out of alignment when changing the caps. Internals looks clean, unaffected by time.

But look, I found the missing little cuing arm inside the plinth :).

Very nice. My dad and I have had a long history of Garrard turntables. They are also great old vintage crafts, but repairing them can be tricky and very expensive. It looks like there are a few places that can repair the Duals, and I've been told that the Duals can last for decades without service. The 1246 is my first Dual, and it has been serviced, and it operates and plays flawlessly.

Still enjoying this, it gets playtime every day. I've put a AT-VM95SH on it, a very good cart and stylus. New TK24 headshell. I replaced the strobe light cap, and now the strobe is a little unstable when turning on. Probably a contact issue with the bulb. Otherwise very good, and tracks 90um with 315hz lateral (Ortofon test lp).
