Hate to ask but: solder back the 21, bite of the pin of 19 cap that solders to the same spot. Do it so you can solder it back without damaging the cap (leave enough lead). Repeat the measurements. Both 22 and 21 resistors, both ends of each to the chassis. Oh, the tube should be still out.
People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
