I picked up an S arm DUAL 1239a. Unusual, now I have to convert it to 110v from 220v.

Hi,

You'll likely need a new motor pulley for 60 Hz use. The motor may be switchable but you may even need a motor for 110 use. Most Duals could be switched for voltage if sold in Europe. Nice Dual!

First time I ever see an "S" armed Dual. Looks like a keeper.

AFAIK, that's the only S-armed Dual model ever made... and even some of those had straight arms.
KentTeffeteller is correct: a 60Hz pulley (part no. 234 454) is needed, and you should be able to make some changes in wiring to accommodate 110V line voltage. Here's the schematic.

rcdis perhaps this may help although it is for the earlier srtaight arm model 1239.

What a cool find please keep us posted on this one.

Uhm, not quite. Actually there were a couple of models Dual offered with either a straight (no suffix or suffix G) or an S-shaped arm. E.g., there also are 1237As and 491As... Reason behind was that a good part of Dual's business was to sell their tt drives to other manufacturers (like Grundig, for example) to be integrated in their stuff. Well, and some of these customers asked for S-shaped arms, even though Dual always preferred the straight variants...

Thanks for all the suggestions on converting the TT. It looks like the drive on the DUAL 1249 is very similar to the TT,I might be able to use most of the drive. The main problem is how to get the platter off, it is a single unit rather than a two part.

The DUAL website also lists the DUAL 1235 as an S arm TT.

Yeah, well, so much for Dual and consequent nomenclature, ey? ;) Anyway, in that case the straight-armed model was the 1234...

Whoops. :stupid:
Thanks, Manfred, rcdis. I didn't know about the 1235.
My apologies for the misinformation.

Here is the works view.

rcdis that turntable holder looks like it works well.

On this site, you will find a few linear arms, very rare for Dual. I wonder what models are missing, as there is no 1229Q listed or pictured.

But one of the sales fliers [I believe] shows a 1229 with an anti-skate dial calibrated for CD-4.

It is one I built , very simple just a base and four dowels

It looks very handy and useful.

The DUAL is up and running, sounds pretty good . I have not finished the base, so it is still a little rough.

This is the frist DUAL I have messed with where the platter is quite a bit smaller than a 12 " LP? Know of any others?

rcdis: Sure, most Dual changers only have 27 cm platters - but there are also single play models with that platter size like the 461/481/491/496... And the platters on the old 410/420/430 are even smaller (a tad below 21 cm).

Good to hear from someonewho knows. Thanks for the reply

I finally finished the plinth for the DUAL. Seems to work o k.

Wow that is a one of a kind! How does it sound?

Souinds remarkably good, I am still trying different cartridges on the TT.

What combination has worked best so far? Have you tried the JICO replacement that you mentioned awhile back?

So far I have tried a Shure ME 97 he and a Grado, the Ortophon and V15 III will be next.
