Home Tube DIY Asylum

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

RE: Where does the current come from?

Thanks for doing the sims, Dave. They make sense.

1) More current comes from C1 (the cap closest to the 2A3) than from C3, especialy if a higher inductance (10 Hy) is used. This is more so at higher audio frequencies (the cannon fire). This shows (as expected) that a higher valued L2 better "isolates" the output tube from the first filter cap. Conversly, a lower valued inductor passes more of the current demand on to fisrt cap.

2) The larger calue 2nd cap (20 uFd) does NOT "hog the current". In fact, it supplies current to the load as much as it takes from the supply. Notice the more or less symetrical capacitor current swing (as mucp positive as negative).

It's the weekend and many things remain on the "to do" list, so I'll add more comments later.
