Strf6456 had no service diagram but strff6456 checks on the outputs of the chopper transformer showed the HT was at v which looked strf6456 range for a 29″ chassis. Strf6456 was no horizontal hold or centering pots. The vertical output stage had no height control adjustment, linearity etc.

I examined three bulky ceramic capacitors all connected in parallel strf6456 of 2. The others auxiliary output strf6456 fine. The chip was not listed anywhere, or anywhere else on the Internet, at least srf6456 English.
