Huh, that's funny... The topic switched from tubes to... tubes.

HAHAHA!!!!

I'm so STUPID. During the process of neutralisation of the pots and after centring the green raster, I didn't touch any of the green related controls after that, as it turns out my problems were quite simple afterall, the keystone was easily corrected with a knob I had mistaken for a green adjustment. I now have a spot on, square picture with mostly correct pincushion. Just have to work on the edges a bit but it's MUCH better than it was. The blue and red HBOW are a teeny bit off but I now have my focused scanlines like before. Absolutely beautiful even with some minor defects. Next time instead of getting all fussed up like an old cat I'll just take a breather and twiddle every pot till I have it right I'll post some pics later.

One last issue - G2 balance.... tones are all off.

How many times have you run the setup now Fujifrontier?

Fuji - Check Your PM.

I'm posting from my phone so I cant check PM till later. Oh, probably about 4-5 times now. I think it's fun. I'm a perfectionist by nature, so the defects that prompt me to redo the setup drive me batshit, like white edges in the centre bleeding red on one side and blue on the other, due to my bad setup. I thhink i'm on my way, we'll see how this goes.

Glad that you got things straightened out. The bow adjustments can be the trickiest ones to get spot on. It's a real back and forthe between the bow and skew to get it right. When making these adustments I find it helps to move the adustment off, so the lines are next to each other, instead of lined up on top of each other, and then move it back to see how they look together. I still think that your deflection yoke on the red may be off, and possible blue too, but this is an advanced procedure to correct, but if you follow the steps, it's totally worth it, and not that bad. If your skew and bow pots are centered, and they appear tilted, you really should make this adjustment. This will make a world of difference in getting the red and blue lined up all the way across the screen. Like I had said, the closer your pots are to center (of coarse they won't be dead on center) the less problems you will have with the convergance drifting apart.

[Fujifrontier]

I'll attempt the blue and red on a day I have free time. The bow and skew pots are maxed out in order to be relatively straight, so you're on to something. I didn't fire it up today, no time. Sunday :devil:

Once you get the hang of setup, there is nothing better than having a nice flat screen to view on. Those ripples can get quite annoying, and there are some inexpensive ways to get a decent screen. On the tightest budget, I would reccomend what I did for my first screen. There is a seller on ebay that deals with rubberized canvas type material, which you use to make your own screen. Get a piece of that, and some cheap 1x2's from any lumber store, and you'll be much happier. This seller has what he calls seconds, pieces that have some minor defect. This is what I bought, and it's hardly noticeable. here is a link to one he has now.

Just go to a local fabric store and ask for black out cloth. It's used to line drapes to keep the light out.

That's what I have. I went to joann fabrics right before christmas and bought a piece of blackout cloth. It's a bit ripply now but it doesn't bother me - yet. I'll fix it after I work up th nerve to touch the yokes.

[Nitmoe]

Aligning the yokes isn't as bad as it may seem. Just make sure you center all of the bow and skew pots before you start. Also, be sure to center all of the corner adjustments (H and V tilt) as well, these will throw you off a bit.

[Fujifrontier]

it's not as clear as it would be if it was a TV.... sorry.

Which one is the one I'm going to turn? There's a few rings and stuff sealed with the glue, as you can see. Care to circle the correct one?

[Nitmoe]

The one you need is all of the way to the front (right next to the bell) The big white part and the coil and magnet ahead of it will all turn as one unit. You need to loosen the radiator style clamp on the big white part, and then there is two-sided tape underneath, where you can't seem it. At the end of the tube, near the neck board that plugs in to the back side, the tabs with the white stuss are for astigmatism adjustment. This controls the shape of the dots produced by the tube, which should be round, and you shouldn't have to mess with that. The coil in between is the convergance yoke, and turning this shouldn't have much affect on the image, certainly not worth messing with it. When yo go to adjust the deflection yoke (near the bell), you want something non-conductive that you can use to turn this by the white plastic part. Just make sure that once you habe this loosened, get the PJ nice and warm, so that it will be easier to move (not so jerky) Once you get to doing it, it's pretty easy. The hardest part is geting ready for the adjustment, especially with this being your first time. You may feel like getting creative in finding a way to move the yoke during adjustment, just make sure to do all of your playing before plugging it back in.

Another note - As for the blackout cloth, I haven't seen any on a roll wide enough for my application. The ones I have seen were 54 or 56 inches wide (can't remember) but my screen size is 105 by 59

[Zebu Fellenz]

Nitmoe-

Check Ebay

[Nitmoe]

Hmm, I just checked ebay, still not seeing anything to fit my needs, some pieces there are wider than 54, but not long enough, and even with these being too small, they still cost more than my one-off piece. Is the blackout cloth better than the canvas?

[Fujifrontier]

I watched family guy for a good while, to get the tubes nice and warm, and loosened B and R yoke clamps. I rotated blue to match the green horizontally. (I would turn the PJ off and then rotate the yoke, and turn it back on again, took me about 4 power cycles) That plastic collar at the top will rotate the yoke, so I had a heavy finger on the red, rotating it niggle by niggle when I brushed my pinky against one of those damn posts near the focus pack, and god damn was that a surprise. The bitch bit me! I now have a tiny blister on my right pinky. I'm quite grateful it didn't do more.. but I got blue and red registered to green horizontally.

The electronic registration took less than 5 minutes, and none of the pots are fully maxed like they were!!!! The picture is AMAZING. I'm never letting go of this little Sony, even though it bit me.

[Nitmoe]

I've been working with cars for some 15 years, and in that field blood sweat and tears are required to get the job done. Glad you had success with the yoke adjustment, and I hope you didn't need that pinky for a week or so. I once took the tip off of my pinky with a bandsaw, it grew back.
