So vts1134, what is the actual voltage at the input side of the choke (L1)? What is the voltage on the downstream side of L1, where the focus coil connects? Is it signifigantly over the specified 255V?
What is the voltage at the downstream side of the focus coil, where it connects with filter C2D? Is it signifigantly above the specified 210V?
Forget 'Y' and 'Z'. That's just the 'floating' heater supply for the damper and not relevant to the problem at hand.

I've found that all of the above locations are above spec voltage, but not so much as to be a problem.
I'm going to continue to look for out of spec voltages. In the meantime my question du jour has to do with L18, the horizontal size control. The schematic calls for an impedance of 35 ohms. It doesn't give it a value range though. Would 35 ohms be on the high side, or low side? The reason I ask is that my horizontal size control is at 3 ohms and spins, but does not adjust in impedance. Obviously broken, but could this cause an over voltage situation on the fly? The schematic gives it two Majestic part numbers, they are B-1.533-1 and B-1.532-1. Does any know what these part numbers would correlate to on a replacement part?
