|Input impedance||1 MΩ // 47 pF|
|Deflection factor||10 mV/div to 10 V/div, 1−2−5 sequence|
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.
