My new Sears set!
 
This is my new Sears TV set that I will hopefully be getting in the mail soon! The pictures are not mine, but I thought I would post them anyways since I am so excited about this set! The green seems to be a little bit weak as was noted by the person who is shipping it for me, but I am hoping that it can be remedied from some adjustments..

Sorry Zeno, I have been having trouble posting images for some reason, and I was trying to get everything sorted out before I finished typing my post...

Toshiba built

Yup its a Toshiba ! Nice tv.... Around '72....
Above the red and green plug on the right, is a square plug with a single red jumper,
that is the focus selector.... Each one does almost nothing..... It's a neato tv, above
average quality build, but that tube just don't focus well....

Good luck ! Great tv you are lucky I bet they are not that common....

Looks like it has plenty of green to me.... That set has color screen
knobs, 2 drive knobs, and that 1-2-3 slide switch above the focus
jumper is kine bias selector.... Very well designed....

You got more than enough adjustments to do everything... except make
a sharp focused picture......

I wonder if there is anyway to improve the focus on sets like this? I know its a problem with most if not all sets with low voltage focus CRTs. Did sets always have pictures like this? If not the surely there must be something that causes it or some way to fix it?

josephdaniel 11-01-2014 08:22 PM

After doing just a little bit of research, I found that some people reported that putting a CRT rejuvenator on clean or a light rejuvenation would bring back the focus back razor sharp, but I don't know if that would work on this jug...

Jon A. 11-01-2014 08:28 PM

I saw the offer and was wondering if you had, congrats.

You might want to try a grayscale adjustment before rejuvenation.

josephdaniel 11-01-2014 08:35 PM

Yes, I know the set will need a full setup convergence, linearity, purity, degassing before I do much to it... I am a bit worried about the weak green, but I have a feeling it just needs to be setup properly as I don't think this set has probably been used in 20 years just as a guess...

josephdaniel 11-01-2014 10:06 PM

I almost forgot. Al made a video of the set for me if anyone is curious to see it in operation...

This has a low focus voltage CRT? I thought all delta gun CRTs like that have the blue gun at the bottom.

josephdaniel 11-01-2014 10:35 PM

It might not, I was just rambling mostly about the focus.

Username1 11-01-2014 10:36 PM

Most are blue at the top..... If I remember right this set has a focus
selection of 0v 150v and 300v, but no way sure... I'm sure about the 0v.

I would not attempt any rejuv. on this tube.... just let it be... It's no worse
than a '66 rca 17" color set I had....

The best you can do is full setup and let it live as is... Bring all three
guns into alignment and you will see an improvement..... Then set up
proper gray tracking, and you'll be ok....

Use the kine bias switch in conjunction with the focus to get the best
focus.... Adjust the screen controls go get rid of those retrace lines, they
are clearly set too high right now.....

There might even be a sub-bright on this set...... With proper setup this
set does get a better picture..... " I Guarountee it! "

Did you get the sams yet....? If'n you get it, you gotta post it, I miss lookin
at that schematic..... Pretty please....?????

Yes, I can post a link to it if you would like to see it. I just wonder HOW good of a picture this set can produce? :D

I would love to see the schematic again....

It's not really a matter of how good a picture a set can produce. It's more about
keeping a part of history, and just appreciating it for what it is....

Low focus voltage tubes had some issues, and you have it to see first hand, it's
not bad, it just is.... Personally I would rather have that set with imperfect
focus, than one known for eating flyback's or vert output transformers...
