Re: Bodges
As a schoolboy I was asked to fix one of the ubiquitous 1950s "five valve" AC/DC radios that had a noisy volume-control.
Taking the cover off I was surprised to see that this was a six-valve radio! As well as the expected five B9A valves there was an Octal too - its socket mounted on a nicely-turned circular wooden pattress.
Only the heaters were wired - across a failed section of the dropper-resistor.
I replaced the noisy V/C, fitted a proper replacement dropper-resistor sourced from a friendly RS-account-owning relative, and kept the 'impostor' valve (was something like a 25L6) which still had good emission despite having been run for hwo-knows-how-long with no cathode-current.
