Description
This is a THT Audio Driver which can be powered by +170/0/-170 V, it is a class AB driver with an efficiency of 76%, can connect speaker from 4 ohm to 16 ohm depending on the output stage. This can be used with 2SC5200 adn 2SA1943 power stages adn MJL21193-94. This works best paired with a tl082 or TL084 Pre-amp.
Also a small software with which to calculate the dissipated power of the power stage can be found here:
