Re: The perils of homebrewing equipment
As well as the "upside-down chip" thing, I've more than once got the wiring of an 11- or 12-pin valve/CRT base rotationally off-by-one and then wondered why nothing sensible seemed to be happening.
And has anyone been 'bitten' by the HT because a design using Octal valves has used the classically 'unused-on-glass-valves' pin on the valve-base as a tie-point for HT but you've fitted a metal-cased valve which expects this unused-on-glass pin to be grounded because it's connected to the metal shield?
