STKS0100 two internal circuit

It is an improved circuit of STK0100. Its internal circuit is shown in Figure 2-99
    . As can be seen from the picture, it has
the same structural principle as the STK0100. It only adds a tube to the output tube to become a three-level push-pull output. The bias circuit
is changed to compound camp.
    STK3102Ⅲ and ST K0100Ⅱ can form a high-power, low-distortion high-end audio power amplifier. It
has few peripheral components and is very simple to assemble. An ordinary rectified power supply can be used. When the power supply voltage is between ±50 and ±60V,
an output power of 100w can be obtained.
