- 40 Watts per channel.
- Low part count, all through hole, easy to assemble.
- One board per channel; two boards are required for a stereo amplifier.
- The board closely follows the published design except it allows using Q11 with any pinout, making part substitution easier.
- The output stage (4x power Darlinton transistors and 4x 0.68ohm emitter resistors) needs to be assembled off board.
