I'm fooling around with some thought of parafeed, but alas I am a poor man, therefore I don't usually build a whole new amp unless I'm fairly certain it'll sound good. Or at least work at all.
I'm wondering would it be possible to have two (2) outputs from a parafeed power stage. To clarify: one tube, cathode biased (/w LEDs), choke on anode, two 4.7µF Solen caps from anode of tube, one transformer between each cap and ground (or cathode).
The other transformer would be say 5K : 4R, to drive a bass cone speaker, the other a P-P transformer in reverse, 4R : 10K to drive an ESL tweeter.
Probably not the most elegant or otherwise best system, but if this would work it'd be very cheap!
Any thoughts?

The impedance reflected by a transformer depend on what is on the other side - the ESL panel is basically an open circuit, a capacitor. In reality it however has a very high impedance or so I've understood. Therefore it would reflect much more than 4R to the other side of the transformer.
Has it been done? Can you put a low impedance primary in a parafeed circuit with an ESL panel on the other side?
