I noticed that the wire going to the Plate Cap from the 6DQ6 Horizontal Output tube was missing some insulation where it enters the cap. I looked closer and noticed that the inside was was corroded green and needed attention.
I replaced the wire with some 20KV wire that I have.
I also used a silicone grommet where the wire exits the HV cage. Dan Jones gave me this tip at his presentation at this years ETF Convention.
All better now.
