Today after I got the CT-100 cabinet settled in the living room, I worked installing horizontal drive and HV adjust pots. I put them on a piece of phenolic, mounted to the chassis with standoffs. I am now able to get a full 19.5kv, but am unsure what the horizontal cathode current is doing because I ran out of meters to attach to the chassis.

After I get back from church, I'll check cathode current to see what it's doing. Hopefully it's OK, and I can put this issue to rest.
