Help me to identify a  transformer passive preamp that was popular here years back. It was made in SE Asia if I remember correctly. I had mine built for my needs at the time. I dug it out of a cabinet the other day.

Hi, I made one out of an old Dyna PAM-1 chassis.I didn't need to drill any holes.I got the design from AudioXpress.



Those are Electroprint transformers and silver wire with GoldPoint pots.....Mark Korda
