Title: Power & Output Transformer Calculations
Post by: TubeJunkie on January 03, 2020, 06:54:10 pm

Hi all, I need someone to check my math, please, for a Power Transformer and Output Transformer shown below.  Do the numbers look right, or am I totally up-in-the-night with them?  Thanks.

That would assume fixed bias of output stage, no special filtering for output stage B+, no voltage drop acros OPT windings, and no sag related effects.
