I have the Technical Training data for your set - description, receiver functions, circuit descriptions, troubleshooting, and adjustments. Last two pages are the schematics for the 958 and 959 chassis. I may also have the Service manual for your set - I know I've got a lot of TS-95x-97x manuals.

Interesting chassis - 7 safety caps from the HOT collector to ground!

Cheers,

Nice, This one needs a convergence adjustment, I suppose the procedure would be available in your litterature?

As for it being somewhat rare, I suppose that when Motorola sold to Matsushita, a lot of people in the US lost interest in the brand maybe?

7 safety cap? Hey that's 3 more than the CC, that's somehting!

Nope - but there is a 2-page description of the convergence circuitry for both the delta and in-line CRTs. Understand that Quasar technical training covers unique circuitry that an experienced technician would need. They don't cover mundane, standard or non-unique adjustments such as convergence.

Your set has adjustments for all aspects - and the board is labeled as to what each pot/coil does. If the red/green or blue is out of convergence in an area of the CRT, just adjust that coil or pot. Out all over? Start with a static alignment with the neck magnets, and then perform a dynamic adustment using the pots/coils on the convergence board. The pots/coils are marked with their function, e.g. TOP BLU HORIZ or RIGHT R/G VERT.

Hope this helps - it would help to know if you've ever converged a TV.

Cheers,

I never converged a delta gun before, I heard it can be quite a challenge even for the most skilled service man!

The Motorola dealers and distributors still kept handling them.
The part of the chassis, you don't see is the power supply. It has the voltage regulating transformer like Zenith and a few others used.
They referred to those as "redundant" capacitors.
Zenith should have stayed with the multiple safety caps, like used in the "E" line, instead of the single one in the "F" line. Cost savings, NOT!!!!

Seems rather risky to me to run a single-safety cap Zenith even if the cap is an orange drop. I doubt that they are immune to the kind of failure the white ones are prone to.
