Perhaps Timmy could trace out the circuit around the 6X5 and 25Z6 and draw a schematic showing how the power supply is wired. Again I ask, does the set actually work or at least do the filaments light up with the 6X5 installed?

No it's not working yet I'm in the process of recapping so if there are any problems later I'm sure I won't be able to rely on the schematic that's out there now. I was just looking into these tubes because they are the source of b+ along with one selenium which will be replaced with a 1n4007 diode later. And now he reign that the 6x5 is known for cathode shorts so there is nothing like a reliable silicon diode and maybe leave the tube in for show, long as it still lights. This is just in case later on I will have this info to do if I could not obtain these tubes. Kind of a backup plan, alternate.
