HDP-1220 Clipper help needed

[Tom Chesek]

I am looking for someone with good solid state skills to analyze the clipper circuit for the Heath HDP-1220 Clipper used with the HW & SB line. The main component used is a NTE724 Integrated Circuit Differential/Cascode Amplifier. You can find a datasheet for the NTE724 on the web and I can email the schematic to you. What I want to find out is the pinout of the IC as it relates to the schematic. All components are indicated in the schematic but the IC does not have it's pin numbers indicated. I am considering building one but without knowing which pin is which I'm at a standstill.

Thanks & 73,

Tom K3TVC
