Full Amp THT NPN V2

This is a THT Audio amplifier which can be powered by +170/0/-170 V, it is a class AB driver with an efficiency of 76%, can connect speaker from 2 ohm to 16 ohm depending on the output stage. This can be used with NPN bipolare transistors (both positive rail adn negative rail, all power stage is NPN), ignore the parts place at the powerstage, only the driver is PNP on the negative rail, the rest of the powerstage is NPN.
