This is the left hand deflection amplifier for the console 64 and is used to drive the Y (vertical) deflection coils in that console.
The amplifier accepts the main trace Y sawtooth along with the inter-trace Y deflection (such as a joystick). The switching is done
in 4 diodes using the inter-trace gate input. This particular amplifier has had some parts removed before we obtained it.
