In other developments, I believe I have narrowed down the demodulator tubes. They are positioned in a hard to reach area, under the support for the yoke. I wiped away the dirt to find R-Y and B-Y pots.





Also, thanks to John's schematic of his prototype set, I did some looking around on my chassis and believe I have found how dynamic convergence is done. I was apparently incorrect when I told Steve that the only wire connected to the convergence pot wiper is the CRT: looking again, there is a wire leading down to a chassis isolated doorknob cap which then leads into small transformers in the vert and horiz sections. I believe these would be the dynamic transformers, based on the wiring I'm seeing. The numbers on the horizontal transformer are T-6942 and vertical is 208T9 and 274113.
