Thank you for all that informations. Last night I soldered new resistors on the horizontal oscillator unit. When brought the set in operating mode again I read that horizontal output current increased up to 450ma.and I switched off the set at once. At the grid of the 6CB5 I found appr. +300v. !!! When I evaluated the unit I found a (small, just invisible soldered) short between c603 and R165 (on the printed circuit). Shame about me! Full B+ at grid of 6CB5. I tested 6CB5: short between screen and grid. After repairing +5v remained at the grid of the 6CB5. Next I will remove the chassis and will operate it outside the set, only for repairing and servicing the horizontal oscillator which is not working. Hope that nothing important more is defect - never touch a running system... hahaha.
