Sorry, but you cannot post entire documents lifted from RM on here.

ESR is only applicable to electrolytic capacitors. I've never found the need to measure it in valve sets. Faulty smoothing capacitors will show up as hum, over heating or low HT. Faulty cathode bypass caps (C3 for example) will show up as incorrect cathode voltage.

For cap values consult the parts list.
