Yes, a choke or a driver transformer is a viable and nice way to split phase, and have a low AC return path for the Final's grids.

The question is, would a direct couple, which requires a CCS on the common cathode tail of the driver tube, be better or worse than a (a) added series coupling cap into the choke and / or (b) if choke or driver transformer, any of the anomalies of a wound transformer, limited bandwidth, phase shifting, insertion losses.

It may be hard to beat 3 inches of Siltech wire or Kimber AGSS in a direct couple.

You can use almost any driver tube and rectifier with that tube. - Ralph 10:43:29 04/09/14 (0)
