Digitech Low Cost Mains Powered Stereo Amplifier

This is a simpl, fairly bullet-proof 18W Channel Transistor Amp and it's surprisingly loud! It's ideal as a small office or workshop PA amp in churche, community halls, etc. Protected from accidental speaker-wire shorts, it will simply shut down and reset after it has cooled down. It is also housed in a sturdy metal cabinet, designed to withstand the typical knocks and scratches.
The front panel featuers a microphone input, bass and treble control, as well as a master volume control. Whilst on the rear panel are left & right push-down wire entry speaker terminals and a single right/left set of line level RCA sockets.
