The input is switched via a frequency-compensated attenuator network which is controlled by the Volts/cm switch.

and dropped after 1970.
This stage converts the input signal to a differential push-pull output. Output of this stage is then passed to the first cathode follower, made  with a [[12AT7]] dual triode, V3863A and V3863B. The output from this cathode follower is then passed to the main amplifier made with a pair of [[12AU6]] pentodes, V3874 and V4874. The final output to the scope chassis is driven via final cathode follower with a [[12AT7]] dual triode tube, V3893A and V3893B, which drives pin 1 and 3 of the connector to drive the vertical amplifier inside the chassis.
 
The tubes are heated from the +75 V<sub>DC</sub> heater supply available at pin 15 of the plug-in connector. This is to avoid any  interference/hum from the regular AC heater supply at 60 Hz.
