Class A amplifier with 2SC3264 and 2SA1295
I have two pairs of 2SC3264 and 2SA1295 transistors and I intended to make with them a stereo class A amplifier rated at 50Wrms/8ohm with wide bandwind and higher Slew-Rate .
Does anybody have a schematic of such amplifier? |

50 watts in class A translates to a minimum dissipation of 110 watts, 55 watts for each device. With proper heatsinks it can be done, but not recommendable. The SA1295/2SC3264 is a higher voltage rated combo, used for high power amplifier output stages. Shame to waste on a 50 watter. Better would be to use a single pair in high bias class AB, something like 20/25 watts in class A and 50 in B. See: Electrocompaniet
