Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: Where does the current come from?

Hooray... some discussion!

Taken to the extreme, one could even consider a really large choke or gasp a CCS to isolate the current loop. (both have problems)

The reason this isolation seems like a good idea to me is each LC filter looking back from the tube is a 2nd order low pass filter so we can shift phase anywhere from 0 to 180 degrees for parts of the audio currents.

I guess the question that needs to be addressed is when you have multiple current loops, how important is the phase relationship between those loops?
