MurrayPro EZMon audio amp circuit

I love small British manufacturers. One of my favourite is MurrayPro who do lots of monitoring gear - we sell a lot of their PPMs as well as timecode bits. For a dubbing rack the EZMon is hard to beat. I had one go wrong at a customer's site recently and a quick call to Tony pointed me in the right direction - IC2 on the audio amplifier card had developed noisey power rails. It's an SSM2018 audio buffer stage is is easily replacable.
