Checked the resistances and they were OK.

Terminals 5 and 9 are around 150V-200V
all other voltages seemed fine.

LED from A3 to center pin is not lighting up

What is your voltage at A3?  Are both halves of your 12AU7 glowing?

Both sides glow and a3 is at around a volt.

I re-soldered the joints and It seems to have fixed the problems. Thanks for the suggestions.
