Although I was born very much at the end of the Valve era, they have always held a fascination for me. While I was at University, I always wanted to build a valve amplifier, but I wasn’t allowed to construct one as a final year project due to the voltages involved. (Which is probably wise, thinking about it!)
I designed a few, and even went as far as simulating some of them with SPICE, but never got around to building any until much later. This section (Coming soon) documents some of these experiments.
