Good afternoon . I salute them. I need information to replace a transistor of an amplifier which is not available in my country, I have already looked everywhere for the internet and it is not available if someone could help me, you are grateful these are the characteristics: 2SA1641 material: Yes polarity: PNP MAXIMUM SPECIFICATIONS Total device dissipation (Pc): 40W Base-collector voltage (Vcb): 30V Collector-emitter voltage (Vce): 30V Transmitter-base voltage (Veb): 5V Maximum Dc collector current (Ic): 7A Maximum operating temperature (Tj): 135 C ELECTRICAL CHARACTERISTICS Continuous Current Gain (hfe): 150 Packaging / Case: X104-1 It has NO equivalent thanks

Actually the TRANSISTOR is not achieved and I think it has no substitute. luck
