I'm servicing an Acram Alpha 3 amplifier. The amp gives clear and nice
sound up to a volume of around 11 o'clock on the volume potentiometer.
Above 12 o'clock the amplifier gives a "bad" distortion on both
channels. Has anyone an idea what that that could be? Almost all
transistors have been replaced already (I have the service manual and
circuit diagram etc). Looking for input and ideas on how to solve that
problem. Thanx in advance

The level it starts distorting at has little to do with the volume
control setting but all to do with the input level. What are you driving
it with?
