SANYO STK3082/STK3062 hybrid. The originals of these systems have not been produced for many years and the market is full of their Chinese fakes, the quality of which is far from the original. Because it is fully based on discrete elements, thus enabling its repair, and opens a wide field for technicians of audio technology, who can freely modify the selection of transistors used while looking for optimal configurations.
The product is a double-sided printed circuit board, in THT technology, with sizes slightly larger than its original, thus enabling free replacement in most applications of amplifiers, where it occurs.
For the purpose of convenient replacement, in the set is a female goldpin-15 connector, which is recommended to be soldered into the amplifier board instead of the original STK, thus giving the possibility of very easy replacement, including still returning to the original without further soldering!
The replacement has been additionally equipped with 2 optional SMD capacitors filtering the power supply, potentiometers enabling precise compensation of zero drift of the differential degree. Thus, we can compensate for any asymmetry of the differential amplifier in any application, so as to obtain a voltage of 0V at the output of the power stage.
In the section photos of the item you can see the scale of reference to the original, and the scheme of the application.
