ВЭФ 12 (Astrad VEF 12 Project) - including a transistor tutorial

[Nowhere-Man]

I am far from being a maths exponent or physics student. Having said that, the science aspect does interest me a lot. I aren't yet sure to what degree I want to be an engineer. Probably I'll be happy with a reasonable level of practical application. I don't agree with you that transistors are easier because the valves are just free electrons. No other atoms involved like antimony and boron. I'll read your postings and ask questions over time. One thing I'd appreciate is do you think I can test the goodness of a transistor without removal? Bias maybe? I was getting only 5 volts on a collector so do you think for an AF transistor that's suspect?
I'll address any other points later if I get free time.
