Default Re: circuit diagrams.

It very much depends what you're working on. With a bit of experience, a 1950s AM superhet radio can usually be completely restored without a circuit diagram because the designs are all so similar. More complex stuff is much more difficult. One approach is to trace out the circuit, but this can be very hard work and there's always the danger of making a mistake. It's always better to source an authoritative circuit diagram if at all possible.
