Questions on new to me 1229

Post by Steelratt » 09 Sep 2019 06:04

Hi,

New to the forum. I posted this to the mail forum, but I found a good deal on two 1229s. One is clearly non-functional, with a broken speed selector, and just doesn't want to work. However, the motor does spin, the thing turns on, so there are some positives.

The second is functional. It came with three cartridges, Shure V15 type 3 (broken stylus), an Ortofon FF15 XE, and a Stanton 681 EEE II-S. It ran pretty well, some noise when the arm was moving, but I cleaned up the contacts with some Flitz metal polish and it went away. However, there is a persistent hum. I'm going to try another set of RCAs, but are there some know problem areas?

Also, is the Shure worth repairing? Are the other two decent carts? The only other player I had was 15 years ago, a simple Project 1 with a Blue Point cart.

As additional info, I am hooking it up to a peachtree 150 integrated, which is going to some nice old Paragon JEM/Jubilees. I forgot how much better vinyl sounds.

All 3 carts are very good. Shure can sound very good with new styli from Jico.
About the hum - does it hum mechanically(motor, idler rumble) or electronically(ground loop somewhere)?
For first you need to lubricate motor bearings on the top and the bottom. Some light (sewing machine)oil applied with help of syringe. The idler should run free when you give it a spin. Drop of oil will not do any harm there as well.
For second check all the wiring path from cartridge to RCA. Also make sure the contacts on the headshell and its sled are making contact. You may want to clean these but the black oxide you see is not that problematic(it conducts electricity being silver). Often the wires that connect the cartridge to the sled have some strings broken and do not give good contact either on cart side or at the contacts. However soldering the contact area is somewhat tricky not to melt the plastic.
Also try to run a wire from turntable metal plate to your amp chassis or RCA shield(- collar). Often this ground is wired to right channel negative at the connection from tonearm to cable OUT.
Download your Dual service manual. Lots of good information there.

The hum problem can result from the bad crimps of the tiny cables in the TK headshell.The crimps are not gastight, when they look like the crimps on the picture. The oxygen had more than 40 years time to do the fatal work.

The insulation is in the crimp, therefore corrosion can happen inside: from outside it looks good. But the resistance of the junction can rise .
There are 8 of this crimps. They can not be soldered easily, because the insulation will melt and burn and make it worser than before. Its possible so solder it, but the insulation must be removed before, and this is not for beginners in the solder job. Here is a example from me with soldered crimps, the resistance of the cables is now 0.2Ohm like it should be.

Those Dual headshells and carriers are well known to develop tarnish on the contacts between them. Ude a pencil eraser to polish them.
I have found that replacing the cables can be a real upgrade.

Cheers,
Alec

These are beauties. There are some issues: I sent a personal message to you. -- D

Organdonorparts can sometimes come up trumps with odd parts like control 'flippers' and so on. They have more than they list.
