protector fuse for ctc15 flyback

[timmy]

the grey scale is done and the hv pot dont work with the bright down, this set has a very good picture, colors, clear. all the tubes are new but i was just wondering why that pot did not work thinking it had something to do with the vert roll but when it warms up 15-20 min no more roll and it would seem like the vert tube 6em7 but tried another and the same result. the bias pot never had to be raised at all, the color set was right there,red,green,blue, lines.but the set does sometimes go into the horiz hold sometimes and have to adjust a few times also when it gets warmed up its fine. i also noticed the vert hold adjust in the front is close to one side of the adjustment, could it be i dont have the vert height and the vert lin set right and this is why the rolling keeps happening here?
