Overview

This is a 60 Watt Class A version of my main 100 Watt Class A amplifier. It only uses two pairs of TIP142/147 darlington transistors in the power output stage, rather than four pairs as used in the 100 Watt amplifier.

The power supply is unregulated and the only protection is a fuse on the audio output and a fuse on the mains power input.

I haven't actually built this amplifier - it was designed for a student in the United Kingdom who wanted something between the 25 and 100 Watt amplifiers.
