The 3 capacitors are the round metal cased ones that can be seen clamped to the inside of the chassis. They're quite good quality ones and some people risk leaving them in circuit, but the reality is that they will have some leakage, albeit well up in the meg ohm range. Don't attempt to remove them, but unsolder the leads from where they're connected to and bend these leads back out of the way. Solder in new replacements of 0.1uf rated at 630 volts - do them one at a time so you don't make mistakes. The capacitors are C2, C3 & C4, the circuit diagram is shown in the picture below. Only attempt the work if you feel competent to do so. If you wanted to try the gram first, it should be ok to power it up for just a few minutes to check what is and isn't working, as it seems that the previous owner has already done this anyway. The two large valves should glow with an only just visible dull orange glow to their heater strings. The valve on the far right is the rectifier and will glow brighter than the others. If those two large valves look like they're glowing brighter than I've just described, switch off immediately!

When working on the chassis it's best to carefully remove those two large valves and store them safely, as if you break them they'll cost you hundreds to replace, so be careful!

The wires that are off should fit on the two missing terminals (someone's been messing with it and lost them), follow the wiring down to exactly the same terminals at the bottom of the cabinet to ascertain the correct ones to connect to. The radio won't receive stations properly without these connected, so you'll have to find some nuts with the same thread to replace them. You may need an external aerial wire connected to one of those bottom terminals to receive stations.
