 Post subject: Anyone parting out a 10L43 Predicta Chassis?

Still looking for a yoke for a 10L43 chassis. I have a 76-10508-24 yoke that was being used with a 10L43A chassis. It had obvious problems, so I stole a yoke out of a Princess I had stashed away. I have a -6 yoke for the Tandem, but not a -14 yoke for the Princess, and I am looking to fix up her majesty for sale. I won't sell it unless it has the correct yoke, though.
If anyone has a -14 yoke laying around, please let me know.

Please excuse if this is the wrong venue to ask.

JF

You could try putting an ad on Video Karma, and the ETF Classified. As a long shot, Moyer's Electronics may have a replacement.

Surely this is a standard design of 110 degree yoke, versions of which were made for many manufacturers?

I wish it were so. Citing my own personal experience only, I can say that a -6 used in the Tandem will "work" in a 10L43 chassis, but it has different inductance and parallel capacitors. And the STRANGEST symptom I had when doing so, was a brightening of the raster at the right side of the CRT. I scoped for hours before I moved the yoke cable and realized that it was related to yoke cable positioning. The "right" yoke does not do this at all. Wave the cable around the chassis all you want....no black level lift on the right side.

Poking around in Rider manuals, I find variants of the part number 76-10508-X of
-4
-5
-6
-9
-13
-14
-16

And like I was told by others here, I don't find a -24 anywhere!

I shall try posting more broadly.

Thanks folks.

The Riders, which is I think a reprint of the original Philco factory info, contains a fairly detailed section on lead dress for the 10L43 chassis.
