In Reply to: RE: Why use a voltage doubler in med-high (400-550V) B+ supplies? posted by LowRedMoon on September 17, 2009 at 10:59:03
I've looked for good primers on the subject, but so far - zip.

If you find yourself frequently repeating the phrase, "garbage in, garbage out," you may need to rethink your system.

Adam, good question. Maybe, it's just a simple case of saving space for application where a lot of current is not needed. Making big transformers for voltage sake only, prolly was $$$ even in their heydays of the 1950-60's.
I've seen doublers in "good" amps. Like Macs and high-end Marshalls. I know that big amps (100 watts+) that have no doublers, like that Hiwatt I'm going to tackle have BIG PT's. Looks like 2/3rd of the cost of the amp is in the PT and OPT.
