you just had to wind some chokes for them.
I can lend Arend my fs-100pf's and if he likes them he could maybe order the one's you had left over.
To infinity and beyond!!!
Should I understand you are not using those copper GM70s I sent you?! C´mon I sent them one year ago! What have been doing all these months?
:-)
and who said that I was going to build something? I just collect MQ Iron because I like having it...it makes me feel rich. And I age anneal my iron for a least a decade. ;)
To infinity and beyond!!!
OK I heard enough!
Bas, I hereby summon your copper GM70 and FS100PF. Name your price :-D
if you like :-)
To infinity and beyond!!!
Appreciate the offer Bas, really nice.
Let me see if they still need breaking in when I'm actually in a position to use them (e.g. I'm still in the sourcing parts stage, obviously).
Thanks again!
Hi Bas:
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.
