Hi to all.
meanwhile I have got a new 6BG6-G. With it I get full horizontal current and full EHT.
After 10 minutes, the horizontal synchronisation run out of control. And the picture became brighter and brighter.
I had to replace the following caps:
In the oscillator: the leaky caps C155 (22 nF), C157 (220 nF). Where I made replacenemts, I kept the old caps in the set and cut only one end of them. The new caps were inserted, so everyone can easily remove the new ones and restore the chassis to its former condition. R179 (100 K) was out of tolerance. Additional, I have replaced C161 (22 nF) due to its electrical loading.
In the D.C. restoration part of the video circuit: C130 (47 nF).
The set is working now without faults. The 10BP4A is tested with 0.4 mA.
