No, Arran, the 8000 ohm section was connected between B+ and ground, so it only served to "excite" the speaker. The 680 ohm section is the one that was used as part of the set's power supply.
Arran, can you send me a copy of that article about the solid state filter choke? Sounds interesting...
Edit/added info: All resistances given are DC resistance, not AC reactance.
If you come up with a way to supply DC to the fields, then you can use an electrodynamic speaker in pretty much any application...which is apparently what the audiophools are doing. But it seems to me that it would be much easier to just use modern PM speakers to get the sound they want. Who knows, perhaps they think these Jensen Super-Giants possess some sort of magical powers or something.
