I've now got all the valves safely removed and bubble wrapped. I'll get around to cleaning them and other valve things later on.

Meantime hope you will indulge me as I embark on some circuit tracing and that someone can offer some advice on the attached picture. Hopefully this shows the V5 (Mullard CV 31) valve base viewed from underneath the chassis - the pencil tip, I think, is pointing at Pin 8 which is the Cathode? If this is correct then the + ve end of the new electrolytic capacitor 47 μF, 450 V is connected to the Cathode while the - ve end is connected to the chassis (more on that connection later). Is this a replacement for C29 which should be 32 μF, 275 V??

I can also see that Pin 5, the Anode, has connections as do Pins 2 and 7 for the Heater. I do, however, note that there are connections to Pins 1 and 3 which according to my research for the CV 31 are not used?? This is what confuses us beginners!

Won't go any further until I'm sure I'm on the right track!
