My thoughts here is that the alignment is not correct. I have never experienced alignment drift on the TV12 TRF series. The TRF unit is built to a high standard and the example I have just serviced has not been touched since 1949 and is still spot on!
It's just a thought but it is possible that you have not peaked one of the vision RF cans correctly. It would be very time wasting to look for a fault that may not actually be present. Regards, John.
