I looked at Pete's drawing and description of the production changes, and Nick's picture and description of his modification, and I understand the differences are these so far:
-Pete describes a production change in the HV regulator circuit that changes R183 (connected to the HV regulator grid and HV control wiper) from 1M to 150K, and moves C141 (connected to R183) from ground to flyback pin 1 (boost B+). (Pete also described nearby related changes to the vertical circuit as well.) -Nick describes changing the HV control high-side from the low end of the DC convergence voltage divider to flyback pin 1 (boost B+) through an added 2M resistor (and grounding the low end of the divider). These changes are independent, it seems.
