Well I'm back from the hospital......joking (adults watch "Trailer Park Boys - Conky takes Bubbles to the Hospital" for some good Canadian laughs) , but I'll write what I got before the wind/rain storm knocks out the power. I'm using a cheap Vici VC99, its 6000count, measures fairly accurately in reviews for a cheap DMM, it just lacks protection, the point is its pretty accurate for VDC anyways.
schematic pics and stuff at the bottom
I've powered it up with just the HV and maybe the front panel connected to the lowV PS. And I checked the marked voltage points most are fine enough, except a +5V pre-regulator feedback point. It measured 7.16-7.19Vdc over the course of 20 minutes. The VAC was 4-6mV.
I wrote down all the voltages, most were within a few mV to a few within 0.2-0.3V, the 2 marked specifically +10V and -5V REF were 10.03, -5.018
In the attached picture I wrote down all the voltages that are SUPPOSED to be there, not what I measured.
Attaching my COM to the rear backplate shielding lowered all voltages by 0.1-0.2V, and raised the VAC to 4-6mV compared to the sheilding/case that runs along by the edge of the board the length of the CRT. On that pretty much all VAC was 2mV
In the end I just went with the backplate to move the DMM 5-6" away from it all.
So that +5VD that measures 7.19V comes from a transformer winding, through some CR354, a 3 pin thing with Schottky diode symbols (u guys will know, a current rectifier ? much to learn yet), then an LC pi-filter, a fuse, then the 39.9k R, (which measures right but I'm charging a cap too and it went to +40k before I stopped) and into the INVerting pin6 of an LM358N dual opamp.
Here's the manual

349 shows the transformer and where that winding goes through the CR and LC pi-filter
That column of transistors with voltages, I measured all them, and the # on the PCB was always written across from the middle pin, but was not always meant for the middle pin (or somethings really wrong). SOme of them varied a bit.
Q479 at the top marked 8V, the upper pin was 5.76, middle 11.87, lower 8.17. But later I had 8.52 on the 5.76upper pin, (I'll double checked but I better check again that it wasn't the lower pin that changed) Most of those were 0.1-0.3V of what was marked
Wow is adobe reader DC ever annoying, can't bookmark pages, and screenshots are distorted, so I used win8 snipping tool
