The plug looks horrible with the live wire by-passing the fuse. Replace the lead if the insulation is cracked. Used double insulated wire as the original.
I mentioned the gromets since you cannot replace them without disconnecting all the wires. take a photo and replace any wires with the same colour. In general it is better to replace one piece at a time. If the wires go inside a transformer, it may be better to sleeve any dubious ones with heat shrink sleeving.

The AVO meter model 7 is a thirsty beast and more suitable for dealing with power electrics. I would go for a model 8 or 9. Make sure it works.

A smaller, more managable digital meter can be obtained for under £10 but they do not like high voltages, they should manage 250V if you use the correct range.
Voltages can only be measured if the set is energised, hence all the talk about isolating transformers.
