I figured out a basic design I could use to build mine from. The National CRM oscilloscope runs on just one fullwave rectifier tube (6X5) powering a 913 crt info including schematic can be found
Here. I hope to adapt this to fit a slightly larger tube I am thinking a 3 inch tube. I also have a Stancor PS-8415 power transformer laying around I would like to use:
primary
117vac 60cycle
secondaries
125 volts @ 15ma, d.c.
6.3 volts @ 0.6 amps
