The Tektronix Type 3A1 is a 10 MHz dual-trace amplifier plug-in for 560-series scopes, introduced in 1962.

Key Specifications

Bandwidth 10 MHz
Risetime 35 ns
Input impedance 1 MΩ // 47 pF
Deflection factor 10 mV/div to 10 V/div, 1−2−5 sequence

Internals

The input signal passes through compensated attenuators and then into a cathode-follower stage made of two 7586 Nuvistor tubes.

Channel switching in ALTERNATE mode is done using diodes. The output stage that drives the vertical deflection plates of the scope uses a pair of 8233 frame grid power pentode tubes.
