Psud and Single Ended Amplifier

Hey All,

I have a question about SE and PSUD. Whenever I model a power supply for a PP or PPP amp PSUD is spot on. Whenever I use it to model for an SE mp I end up with way too much voltage? Then I get stuck have to clamp it down with resistors. Is there something I'm missing?

Also, if using a tube rectifer say GZ34 or 5U4 do you still halve the unloaded secondary voltage when inputing the power transformer specs?
