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.
Tektronix added a 260 ns delay line to the 3A1 to make the 3A6.
