So i found this pentranic 1019 wich i though it was a weiyah 688, but thanks to LilShawn and an old topic founnd here, i found the correct model, its a 20/21 chassis, that it was just working fine on a 20 inch monitor, but the monitor its all scratched so i decided to replace the monitor (tube) im sorry, with a tv tube i though it was a 20 inch but turned out to be 19, since im not an expert i asked an old friend of mine and both tubes, have around the same values, according to my friend they are compatible, so i desoldered the cables on the scratched tube and solder them to the new tube, and i had image, is just not fiting. The horinsontal is just a bit off limits, wich im ok with that, but the vertical does not open all the way. Playing with the knobs, it looked like one of the knobs was acting weird as for amoment it would open the vertical all the way just normal, but it started to to shake alot in the bottom half. So i inspected the chassis, and found one little black part that looks like a transistor, but im not really sure what it is, and it was all bend and was shorting, and i just put it back to normal, now after this, no matter how i play with the knobs, the vertical wont open all the way, not even the way it was doing it when the knob was acting weird. Lowering down B+ makes the horizontal fits just fine, so i got a feellling that maybe doing something to this can make the image fill the screen just right.
Anyway heres the schematic lilshawn provided on the old topic, and hope someone can help me fix thix thing.
Picture shows how much i can open vertical, also im using a windows 7 x64 pc with emudrivers, that was working just perfectly with the old tube.
