Well, there are 2 ways of looking at it, but Friday was potentially a "what made your day a crap one?" Because after a crap week, I settled down to listen to some vinyl myself, only to find the right channel had almost completely dropped out. This half an hour before bed. However, I am fortunate that I am friends of the amp designer, so my day was a good one cos he fixed it for me the following afternoon, with a new pair of perfectly matched valves and a few small updates that had happened since I got mine as a preproduction unit when he first developed them. All for a coffee and panino and an unspecified favour to be cashed in at some point in the future. So the tunes are flowing without interruption. Result.
