I have the service manual, but it's the electronic version and it's not clear enough to note all the voltages on the socket. These are the ones I can read okay, but the 13 and 4 are blurry:
Pin:
2- 143V
11 - 142V
6 - 142V
7 - 36.4V
12 - 36.4V
3 - 36.4V
5 - 540V
13 - 640V
4 - 540V
9 - 3.5kV
If those voltages are correct, I can do all but the last 4 as my meter only goes as high as 500V. Oh, and are those AC or DC volts?

Without going into much detail.........
I always pulled the IF jack when doing a grey scale if it was easy.
This gives a totaly dead raster or line.
Pin 9 is focus so not to worry for now. Pins 5-6-13 are G-2 and
may concern you. Measure at the chassis unless you have a test socket.
The only thing in the socket is spark gaps & 1 K resistors.
they do go bad but usually the focus pin from too much focus voltage
or constant high humditity.....
I highly recomend a rebuilt Fluke meter
off e-by. Got them for both sons & do more then the cheapo
meters. Also can drop them, hit people with it etc & will keep
running. Just be sure it goes to 1 KV DC. They run abt $75
but will last your life. Beond 1 KV you need an HV probe..........
