The Far East quite a popular hi fi BJT transistor amplifier module for full power output transistors 4 2SC 5200 and 2S 1943 should be tested one at each used test voltage +-35v accordingly, the power will be lower for full power supply voltage pretty high, build and test stages be careful of capacitors and transistors link circuit voltage without checking whether it is correct to give.
Maximum supply voltage + / – 95V.
Output power 255W RMS 8 Ohm speaker with 4 ohm speakers with 400W RMS
Frequency Response 20Hz – 20Khz
Input Sensitivity 1.25V RMS
Input impedance 39 pounds. ohms.
