It's the same on the 10BP4 and the 5" technician tube so it's not focus coil position since the 5" doesn't use it. Any thoughts anyone?
I suspect crosstalk between horizontal and vertical circuits...possibly a filter cap on a power supply shared by both is not doing its job. Do you have an oscilloscope?
