[Dealbreaker]

Hello-
Been lurking for some time, and I just want to send my thanks and gratitude to this site for freely passing out knowledge and real world experience to folks like me who have a passion for the tube sound, but not much knowledge of what's "under the hood."
I have a smattering of electronic know-how, I would say above average in home AC wiring, decent solder skills, can navigate a schematic (at least know what's what, and can usually trace a signal path), but there are a couple things I cannot get my head around.  And maybe this is a separate thread in a more focused section?  But here it is:  Why does every tube amp send the hottest portion of B+ voltage to the output transformer?  I realize that this voltage goes to the output tubes, but surely they could be powered with a different discrete path?  What is so vital about connecting the two transformers?  I ask this knowing it has to be so fundamental to folks with actual design knowledge that I'll probably be asked to come back with a harder question next time...But yeah, this keeps me up at night. Why can't the high voltage/low current audio signal leaving the output tubes just go straight to the output transformer?  Why do we need the hot leg of DC going there too?
Thanks in advance.  I'll hang up and listen for your reply.

Hi there and welcome aboard!

Our kind moderators may (or may not) move your question, but the simple answer is that each "stage" of an amp has different requirements.  And, we need to "decouple" the stages.   

Best thing to do is go here:  http://www.valvewizard.co.uk/smoothing.html  This is the best explanation I have seen.
