Sounds like you don't have the over 300VDC power that is needed. The OA2s each light up when they regulate at 150VDC, if only one OA2 lights up, then the B+ is less than 300VDC so you have to solve that. Start with the B+ filter caps and the 6X4 tube.

As I understand this, one tube is lighting and one is not. And it seems to me that "no change" could be taken to mean either the same tube stayed unlit, or the same position stayed unlit. I think that's the reason for trying again, for clearer communication!
