1976 Quasar console

[Dreamsbeard]

About two years ago, I went on a little road trip (approx 500km round trip) to pick up this 76 Quasar console. Got it from an elderly couple that bought it new in early 77 for 861$ (they still had the receipt for it!). They told me that the TV had been in their basement since about 1991, and that they rarely used it since then. They where happy to see it go to a good home.

The reason, I bring this up now, is that I kept the TV in storage at my stepmother house since, but in a few weeks I bring it home with me, and I wanted to know more about it.

Obviously it's not as collectible as a real Motorola works in a drawer, but it's still early enough to be intersting (to me anyway ).

Please feel free to share your thought about this one!

Thanks!

My grandparents had the same set. My granpas brother was the local quasar dealer (marsden TV in Edgerton, WI) sadly its now a Subway...set was still going strong when i saw it 2 years ago.

I don't know much about Quasar...Mais tu as fait une bonne affaire ...If this set's working fine, it's a plus .

Quasar WID sets, Moto or Jap, are all showpieces in my opinion.

Hey , thanks buddy I really quite like it. It may not be a CC flat chassis, but it's the nicest console I have for sure.

I'd be really interested to know what its strengh and weakenesses are. Zeno?

Where I worked there were not many Motorola / Quasar sets. I
only remember putting a few hoz outputs in them. As a rule
anything Panasinic made was of good quality. Usually very easy
to fix & good runners.
Later in the '80's we did start selling Quasars as a lower priced set.
They were good except bad flybacks.

Um, rare in these parts! Your set is a "Super Module Chassis" set - 75% of the set's circuitry is on the SF-panel super module. The two Super Module chassis produced by Matsushita/Quasar were the TS-958 and TS-959.

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,

Sounds like a fail safe design that would likely trip the breaker before the HV climbed high enough to do significant damage.

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.

Does this set use a delta gun CRT? I'd be interested in knowing who made the tube (the EIA number on the tube label should tell us).

Of course it does! V25VCZP22
