It had to happen sooner or later, but I still feel very upset at his death. I had several items of Sinclair stuff in my youth and so did my schoolmates. Between us I recall a Z12 power amp, two Micromatics, A project 60 pre-amp, a project 60 stereo tuner and several Z30s. Plus a few Cambridge calculators. All of them worked a treat, although I did manage to blow the backside out of one of my Z30's by shorting the speaker. We even had a disco amp made from two z50's and a PZ8 PSU. Despite some pretty aggressive use, it never let us down. Farewell Sir Clive, you'll have a bit more time in the lab now.
