I'm glad you experts see this as a complex matter too : - but thanks Ian - you brought me to a much simpler solution in my example. Alltough the -20dB input pad is not the problem (this is original TAB - design and certainly wanted) - the problem was a messed up pcb connection to the 600T-Attenuator pot.ruffrecords said:I am confused. On the one hand we were discussing a Sowter output transformer and next you are talking about the differences in input transformers and the effect they have on the sound of ribbon mics.
Let us be clear. I am not disputing there are differences between modern and vintage output transformers. I agree dcr and inductance are related but the relationship is complicated by the AL of the core and the thickness of the wire used but other than that there is no advantage per se in high dcr.
BTW - any experience with the Sescom line (think 80ties, but not much info found)? Got a large pack of these mic and line trannies for about nothing - so if it's crap no problem.
