Stevieboy, you have a very nice example of the 1219 with an original
Dual base and not the cheap United Audio one. United Audio was Dual's
US reseller and made lot of compromises to save costs like making their
own cheapo base, and also eliminating some of the Dual damping weights
to save on shipping costs.
The base is fine, and with Dual's nice sprung chassis, you should give it
a try and see before deciding to make another plinth.
The idler wheel seems to be in very good condition too. I think this
machine will turn out to be a beaut with a little bit of TLC.
The 1219 and 1229 are mechanically almost identical, except that the 1229
has the strobe feature. To accommodate the strobe disc under the platter,
Dual eliminated some of the ribbing on the underside of the platter. Hence,
some feel the 1219 is the better machine due to the extra rigidity of the platter.
These wonderful machines have the reputation of being some of the most
complex machines, evoking comparisons with "Rube Goldberg" creations.
However, with all the excellent info posted on AK by Seth (NoTransistors),
Bill (bohhey) and others, it is possible to restore the machine locally
to excellent working order. If I could do it, I am sure you can do it much
better. Send me a PM with your email id and I'll mail you a zip file of all the collected
info I have (incl an excellent servicing guide by an ex-Ford engr, which
is much better than any official Dual doc).
Before you do anything, do not attempt to move the single/multi lever,
unless you have lubricated the mechanism and replaced a rubber
collar around the single/multi shaft. This is absolutely critical, or you
could fatally damage the so-called "dearing ring" of the tonearm, a part
which is, sadly, no longer available and will render the tonearm useless.
(a workaround to fix it into single play mode has been alluded to by
Seth, but has never been elaborated on).
These Duals are fully automatic machines, and the tonearm is tightly
coupled to the rest of the mechanicals. I do not see an easy way to
integrate another tonearm into it without a lot of effort.
Anyways, the 1219 tonearm is quite well regarded, so you may be fine with it.
Please see the list of "failure points" from Bill (of fixmyDual), which you
will need to address while servicing.

Very importantly, you must do the following stuff, at minimum -
1) Replace the single/multi rubber collar. The nearest suitable replacement
I could find was a small length of sthethoscope rubber tube, as suggested
by Seth. I could not find a suitable injector O-ring, which is used by US folks
for this collar.
2) Replace the Steurpimpel. I used a 5mm piece of coax cable inner insulation,
again suggested by folks on AK.
3) Oil the motor. The info I'll send you will have all the details, and I
posted a bit of it on the other thread.
4) Clean all old/dry grease at the metal-metal linkages and replace with
with lithium grease. Use the grease sparingly.
5) Clean and re-grease the speed select and start-stop levers.
6) Clean head-shell contacts and muting switch.
7) If the tonearm damping is not effective, you will have to replace
the 500000wt silicon damping oil in the cylinder. This is a very tricky
job, and I misaligned the tonearm, and took me a few days of reading
and experimenting to get it back in order.
Also, I can send you the fluid (you only need a very little of
it, maybe 5ml max).
To remove the motor for lubing, you will need to disconnect the wires from the
K3 power box, a nasty bit of work, and one of the worst things Dual engineers came up with.
You can check and replace the spark suppression capacitor inside there, as suggested
by Rajiv on the Garrard thread. I used a X2 rated Epcos (German) film cap, got from my local
electronics parts vendor. The value is in the service manual (download from VinylEngine), and
is 0.01uf, 400V as far as I remember.
You can pick up a multi-play spindle on ebay. Personally, I don't use
multi-play as my very limited vinyl media is too treasured to let them drop
Best wishes for the restore. It will be a challenging job, but I am sure
the end result will be worth the effort.
