Internals

The final stage of the 455 vertical amplifier employs a differential pair of triple-stacked NPN transistors. The purpose of the stacking is to get higher voltage swing and to eliminate the need for a heat sink.

The 455 uses a linear power supply.

Triggering is done with 155-0121-00 chips, one per channel.
