I have a mic the late Oliver Archut built for me that has the coupling capacitor on the minus/ground side of the output transformer primary to ground, instead of between the plate and the + side of the input transformer. Not sure I understand all the implications of that. I've never seen another mic built like that. Usually the coupling cap is between the plate and the + side of the output transformer, in order to block DC from the plate. BTW this is a plate follower circuit. Just seems like it might not a good idea to subject the tiny windings of the mic output transformer to any DC, no? But I also figure he had his reasons for doing that. Or maybe he was just in a hurry. Curious what you guys think. Thanks!
