A lot of people here doing low power tube stuff seem to be looking for a cheap source of these. I'm wondering if using a simple 6 or 12V secondary transformer with dual primaries would be the easy way to go, at least in 120V land. Power one 120V winding, and use the other for HV with a doubler.
Consider the Altec 436C supply, schematic attached, they do similar and get a happy B+. The only caveats being to double the current rating because you are only using one primary, and possible issues with the unexpected voltage deferential between the two 120V windings.
