The results of this evenings work. The CRT is receiving the full 4KV on it's anode. Video drive to the cathode is 35 volts P - P. The 2.5Mc/s definition bars are visible.
The ion burn doesn't look so bad now.
The receiver is still operating from a reduced HT supply. The 10Kohm resistor in series with the negative tag of the reservoir capacitor will be removed in due course.
