I have been giving my 6550 a bit of attention and have been upgrading some of the capacitors.

I have come across C23/24 and R47/48 which are on the schematic but are not on the parts list or shown on the general arrangement diagram. Does anybody know anything about them? It seems to be some kind of bypass capacitor between the rectified power supply and the ECF80.

The capacitor is a 100pF 630V and the resistor is a 15k and looks like a 1/4 watt.

I thought I might replace them while I am there with a 100pF 630V polystyrene and a 15k 1/2 watt resistor. Is this a wise thing to do?
