The purpose of this exercise is to eliminate the B+ as a cause for the low volume. At this point here's what I would do: I have several bad octal tubes in my "bad tube" box specifically for this purpose. I remove all the glass from the base of a tube then solder in two 1N4007 diodes in place of the rectifier diodes. Now I have a substitute 5X4. It's quick and simple. But, I m thinking the volume trouble may be elsewhere.
