Yeah, but he said he replaced 127B with a Dale chassis mount,which should have no connection to the yoke?
I can't see that R127B supplies any source voltages to the horizontal or vertical circuitry. Looks like it supplies negative bias to the video and sync circuits. R127B is in series with the negative voltage on the center tap of the 5U4 transformer winding - that feeds the focus coil and Ion trap, which is also in series with R128B-C and continues to ground. So basically you have a negative voltage source being divided across several resistors all in series to ground, negative bias voltages picked off to bias the video and sync circuits. Have you slowly powered back up since you replaced R127B?
