Various kinds of vertical out IC configuration.Ac coupling -connect from the yoke deflection output to a coil connected directly.Dc coupling - connected the output to the coil through a capacitor deflectioan yoke. Electrolityc Capacitors (usually worth 1000u/35v). This configuration requires two kinds of voltage (the voltage mirror plus-minus).Dc input coupling using diffferential - uses 2 input from the driver IC.

What really drove me to build this 6EM7 amp was an idea about amplifier layout. Looking back at most of my tube designs, and most of those on the internet, revealed a very typical pattern. Amplifiers tended to be flat chassis with tubes and transformers above and electronics below. From a historical perspective this makes perfect sense. Metal chassis were built this way to facilitate packaging and assembly. When people started to make tube amplifiers again, they just removed the upper case and built in the same way.

The TDA9302H is a monolithic integrated circuit in HEPTAWATTTM package. This is a high efficiency power amplifier for direct drive vertical rolls from the yokes of TV . This is intended to be used in Color and B & W television as well as in monitors and displays .
