I'll let Al answer the technical stuff. He guided me through making the transformer version with the R-Cs on the secondaries as a quickie alternative to the chokes. I have no experience with the chokes, but this tranny version DEFINITELY works! Works well. You can immediately hear the difference when you switch it in and out; even my kids can hear it easily.

On the other hand, be aware that all these core/coil devices are subject to some level of vibrational buzz. You have to mechanically damp that in the trannies, that's for sure.

Yes. You will need to connect an R-C network to the secondary. - Al Sekela 22:05:03 04/27/07 (6)
