V4_70/120W amplifier
### DESCRIPTION 70W/8ohm, 120W/4ohm high quality power amplifier. Frequency range 2Hz-270kHz. Distortion 0.0002%, at 60W/8ohm. More than 20 was build in the last 2 years.
### TECHNICAL DETAILS / COMPONENTS Gain is 16 (24dB), input impedance 20kohms. Input stages are use KSC1845/KSA992 transistors. The output use 2SC3519/2SA1386, or NJW0281/NJW0302, or any other compatible. Resistors are DALE RN55/60/65, capacitors are Elna Silmic II. Power supply is +/-40V 200W/channel
### LEARN / TOPIC / BUILD INSTRUCTIONS Be careful, as there is no protection against overload, or short circuit. I was removed them to get better sound quality. This order use 2oz copper, however the amplifier works with 1oz too. If you need more information just drop me a message: sajti@hotmail.com
