I have a BH15 112. All the modes I see are for the BH5. But they seem to change over to the 15 with a few changes. Both the scematics and modes are here Rowbinet.
I was wondering if the wires from the pt that dead end on the board "yellow wires". On the the BH5 they are 5v but on the BH15 they are 6.3v would the same tube be used if I wanted to install a tube rectifier?

Not quite, on the BH5 schematic the unused PT winding is a 5V and on the BH15 schematic the unused winding is 6V. My guess is that this is most likely a typo, since 5V and 6.3V windings make more sense than 6.0V and 6.3V windings. My advice would be to measure the voltage with a DMM. If it is 5V, then yes you would use a 5V tube rectifier, although not necessarily the same one as a BH5 since your current draw is essentially doubled.
