:b Hello all,

Does anyone know where I can obtain ideas on how to construct an IEC/NAB circuit? Where can I go to find this information? I do appreciate all comments and suggestions. Thanks all.

Didn't Tony Ma share his schematics?

I'm sure you could find Ampex on line somewhere.

Hi Jazzbo
There are two kinds of EQ circuit (CCIR/NAB) active and passive ,so first thing is to make sure which one is your preamp's design, the different between IEC and NAB is only some value of resistor's difference, but it work out different in passive or active design, if in passive design, it is more simple to work it out the different value between IEC and NAB
