about the use of caps in a voltage doubler. I am restoring a Lafayette 250A that uses a voltage doubler. I noted in your article that you 3x the power supply caps off the diode, the ones in the Lafayette is 250 ufd, so would you recommend a higher value? thanks!

Not Mike, but the answer is yes. If you have the room, install the 820 μF. parts Jim McShane sells. You also need inrush current limiting thermistor(s). Clanging power trafos are to be avoided and "popping" fuses are no fun.
BTW, while the "beast" is on the bench, upgrade the SS diodes too.
