Hi there, I am running into an issue in which the K4600 on my gorf has failed. It was displaying a blank screen until I turned up the brightness, but was met with no horizontal deflection. I also noticed that I had no neck glow but could hear HV. Checking I measured across the heater 0V and with the HV some 12kV. I also checked the B+, it is a little high at 133V, but I cannot adjust it because of the glue in the B+ pot (I will resolve that sometime this week)

Any suggestions on where to start with this one? I recapped it a few years ago and replaced the large paper capacitor as well (originally tested bad) and it was working fine up till a few days ago.
