Ok.
1. You said in the beginning you checked your tubes. I was operating under assumption you did. So you didn't.
2. The votage should be negaive.
Now, either check tubes or replace them with a known good ones, at least 14A7 to start, or get a sig gen.
We are walking blind.
If pulling 14A7 or 7a8, does any of it bring the voltage to 0?
