Hi Reset.
Thanks for the info. Fortunately the Spider coil has plenty of taps and the one I settled on gave the best compromise on the ALD, funny enough taps either side made little difference with the OA47, with the Galena it was even further up the coil before it worsened.
The odd thing is with the battery, are these ALD devices not as "Zero" as we are led to believe and all I'm doing is giving it a little forward bias or it is actually turning it from a passive to an active device?
I'll pop up a diagram sometime tomorrow. This one though gives the general idea, all I have added is a 1.2v cell in series with the phones, positive to the EPAD.
PS the Phones are marked 6000 ohms, they are of German manufacture from the late 20's.
