Hi everyone, forgive the noob question. I have an Antique Sound Labs T1xDT transformer based passive preamp. It has 2 outputs, 3 inputs, a "direct in" and a "tape out". I need a tape loop to which to attach my digital room correction processor and I have been told by a retailer of same that it is an easy task to rewire the unit to effectively "make a tape loop". They were not forthcoming about exactly how to do it, of course. Just wondering if that's even doable and if so, what would one do? I have some soldering skills and it would seem to me that the wiring in passive preamps is pretty simple, or am I way off here? Thanks.
