Scott Swartz	Re: Homebrew tube dist. question The 5Y3 is specifically designed for for full wave rectification with a power trans that has a CT. It could be used as a half wave rectifier by connecting one of the tranny secondary leads to one of the 5Y3 plates (pins 4 or 6) and grounding the CT, but this will require much more filtering. Lets assume the trans is 300-0-300. Since you mention you considered a bridge rectifier across the 300-0 terminals, that would give no load DC of 423. You can get the same 423V using the full wave arrangement the 5Y3 was designed to be used in. The trans secondary leads go to pin 4,6 and the trans CT is grounded. Look at any guitar or hifi schematic with a tube rectifier to see what I'm talking about.
