Thanks for the info Phil. Do you or anyone else out there know anything more about this transformer swap? Any R's or C's need to be changed? I've opened up my T3 & the stock transformer is held in place by some buss wire soldered to pads on the circuit board. Should be relatively easy to remove. I downloaded a PDF on the CineMag 2480 and will open up the T3 again soon to check for size fit. I'm pretty interested to see if I can eek some more performance out of one of my favorite mics. This might slow down my lust for other mics.
