Hi I am restoring a RCA rca CTC16 which was modified by RCA for 240v 625 line 4.43Mhz NTSC / PAL see

I now have the TV working in both color standards but still have problems which people on your forum probably have experience of.
One the height reduces as it heats up.
Two the horizontal lock drifts and is poor.
Both tubes have been changed.
Thanks
Keith
