I do have two pairs left... but they are on hold for a customer in Canada.
How sweet of you to offer a loan to AJ.
Interestingly--- I was halfway smitten by the airgapped design that I penned just a few evenings ago for the operating points that AJ mentioned. It's a bit short (in my estimation) in L--- iirc, I calculated 43H. Not terrible--- I had calculated the power response to be 3db down at something like 26 or 27 hertz.
And then you can do silly things (smile here) like putting huge 50 to 75 mfd caps in the ultrapath\WE arrangement so that you can avoid (smiles here as well) that darn pf cap of four to six mfds.
For parafeed--- I would encourage AJ to perhaps adjust his operating voltages and currents to make them dovetail into the 5K impedance of
the EXO-050.
Bas someday we have to meet up.
