['LIVEWIRE?']

I agree with FStephenMasek. I'm in the process of repairing a Bush DAC90A, and have already replaced all the waxies, without bothering to test them-they are the best part of 70 years old and will all be electrically leaky. The resistors I have checked, and will replace out of tolerance ones. When undertaking these kind of jobs I metaphorically wear my 'service engineer's hat' i.e. I replace faulty components with the nearest equivalent modern ones. Waxed paper caps. I replace with yellow LCR or similar poly. wire-ended types, resistors usually with 2 watt metal film, since these are similar in size to the old carbon composition type. I don't re-stuff old components unless I'm working on a particularly rare radio.
