The stabilizer is designed for high power bass amplifier. It has an output voltage of 27 V, load current up to 3 A.
The bipolar power supply, which is made on the complementary transistors CT - CT. Both shoulder stabilizer is made on the same pattern, but in a different shoulder changed the polarity of the capacitors and transistors used a different structure. In a small range the output voltage can be changed by the resistor R4.
