Hence my term "unitized", which I thought to give the basic idea without going into excessive detail on an obsolete device. In connection with similar low-power high-voltage supplies, I could also have mentioned vibrator-transformer supplies, run from DC battery, used very often in lower-power tube gear, such as auto radios and even photo strobe flash. The high-voltage DC was obtained from the transformer secondary by either a traditional tube (very often cold cathode gas) rectifier, later solid-state (selenium or silicon) or an additional set of contacts on the vibrator itself. Notorious for kicking up all sorts of RF noise. But this is way off-topic. --Chuck
