The Tektronix 10A1 is a differential amplifier plug-in for 647 scopes. The input amplifier uses 8056 nuvistor triodes for the input cathode followers. The 10A1 is a comparator, meaning that it has a built-in precision variable DC voltage source that can be added or subtracted from the signal voltage.
The 10A1 was designed by Les Larson.
