if friend Oscar that part is the same, although the vertical of this chassis is the la78141, now I leave it on for testing with the + b in 123v and I burn the regulator, I think for the reduced + b, to reach 130v I have to turn at maximum the potentiometer, this will be normal.
r 561 100k, r 554 2k4, I put a regulator cq1265 the + ba 120 v and I burn instantly, it will be the yoke, the horizontal measures 4 ohm and the vertical 6.4 ohm, and change the electrolytic of the horizontal and vertical, those of the source, thanks for your help on this fault, greetings friend
thanks Oscar, the maximum potentiometer gives me 120 v, going down halfway gives 113 v, I suspect the yoke that measures me 4 ohm horizontal and 6.4 ohm vertical, although if it was wrong I would also melt the horizontal, something is happening to me, I'm going to keep checking, greetings
