Checked resistors in yoke, and most of horizontal circuit. Nothing is way off, but not dead on either.

Read -30V on G1 of HOT, versus -36 on schematic, and 105 versus 126 on screen of HOT, with 225V B+ versus spec of 216 (probably due to silicon rectifiers),

Attached is photo of set tuned to inactive channel, with contrast and brightness tweaked to emphasize problem.
