Ok, this is important!

Once you've confirmed that there's no remaining electrical connections to the two positive terminals of that original double capacitor, I think it's time we had a list of HT voltage readings (full mains, no lamp limiter), but keep an eye on the 'can' temperature of those remaining electrolytic capacitors while you're making them.

So with your meter negative probe firmly connected to the chassis, and starting off with the meter set to its highest DC voltage range, take, note down and post the following readings:-

1) The hot end of the new reservoir set of four capacitors.
2) The positive end of C48.
3) The positive end of C47.
4) The positive end of C43.
5) The positive end of C38.
6) I would also like to see the anode voltages of the three preceding valves.
7) Also, the voltage on the screen grids of the two pentodes, ask if not sure.
