A60-V1.1 200Wx2 Two Channel Amplifier Board Kit 2SC2240 Power Amp Board Refers to A60 for Accuphase

A60-V1.1 200Wx2 Two Channel Amplifier Board Kit 2SC2240 Power Amp Board Refers to A60 for Accuphase

Features:
- 2-channel amplifier board
- PCB board with double-sided immersion gold
- After our comparison, thanks to the excellent circuit architecture, the precise HIFI transistors 2SC2240, 2SA970, 2SA2705 and 2SA1145 pairing, and countless corrections of the circuit parameters, it is better than KSA50 in the low frequency effect, the sweetness of the vocals and the transparency of the high frequency
- Board test: The circuit has a rectifier circuit, so you only need to connect it to a transformer, and there is no need to connect a rectifier board. It is very convenient to wire and install. The fully symmetrical architecture with the precise pairing of transistors makes the midpoint very stable without debugging. Adjust the quiescent current of power transistors to 100-300mA per transistor. The board has one test point, and the voltage drop at two ends of the test is 20-60MV
- The resistors of the circuit are 718 resistors. Japanese component for Omron is used for protection circuit
- Input transistors are Hifi 2SC2240 and 2SA970 precision matching. Driver is NJE15034/35 for ON
- 6 pairs of 2SC5200 transistors, 1943, or 4 pairs of Sanken transistors can be used with your high power transistors. Transistors for ON can also be used
- A60 circuit module with current feedback. The main feature of the circuit is the use of complementary push-pull circuit from the input stage to the output stage. This makes it easy to achieve a slew rate of hundreds of volts per microsecond, which is quite good for capacitive loads
- Japanese component for Omron + UPC1237 protection circuit ensure that the output is safe and reliable, protecting your speakers
- Japanese 50A Sanken bridge rectifier
- Midpoint servo circuit for more stable output. Thus, no need to zero

Attention:
- Remember to add mica sheet when installing high power transistors, and the mica sheet must be coated with thermally conductive silicone.

Specifications:
