I have a plastic cabinet tabletop 19DC12 and my focus pot is in the "vert centering" apron hole as well. I thought it was an upgrade mod.

I also had a 19DC11 set that was otherwise identical and had the divider resistor like Tom's earlier set. The focus control was mounted on a fiberglass board at the fly and the control had a long shaft that stuck out the back.

As I recall, the focus was better on the 19DC11 but I gave it to Bryan Gadow in one our frequent set-swaps.

IIRC the ones with the glass board all had a big disc cap that would arc.
The caps were pulled & a tripler kit subbed. The original tripler was
a weird looking thing like a ladder & was red. Not too many
came that way. There were a lot of varieties in the hybrids HV.
I only did one FBT on one & it was a big kit & included a tripler
IIRC.

I've seen that trippler and I understand that it was a Selenium stack and German made. I omly saw one Zenith that used it.
