In Reply to: Where can I locate a primer on the implementation of the tube voltage doubler? posted by Iczerman on December 30, 2008 at 08:54:11:
JMO, voltage multipliers are best done with SS, not vacuum, diodes. Anything resembling decent regulation requires the use of LARGE filter capacitors. Caps. large enough in value cause vacuum diodes to arc over, at power on. ;>( Another consideration is the matter of multiple forward drops.
The suggestion employ damper diodes is as good as it gets, using vacuum rectification, as they are reasonably tolerant of capacitance and exhibit comparatively small forward drops. A pair of 6AU4s, along with 2X dedicated 6.3 VAC heater windings MIGHT yield a satisfactory result.
