i guess i could turn on the set without a picture and see what the "free running" speed of the vertical is, just for fun...i will do that if i have to remove the chassis again.

do you have any clue as to why i put the modulator on channel 3 and can only tune in on channel 5? also if i put the modulator on channel 4 i can tune in on channel 6 and so on. this set uses a turret tuner and its different from the wafer tuner used in the American sets
IIRC different regions of the word that used CCIR/PAL (and for that matter different NTSC regions as well) used different channel frequenies from other regions. Some countries had FM in different places and planned TV arround it different, and places like the UK had competing TV standards like 405 squatting on some bands.
Your tuner probably comes from a different region from your source....That or your tuning knob is in properly indexed.
