Civic Radiogram XR5930 - UK Vintage Radio Repair and Restoration Discussion Forum

I am in the process of renovating this radiogram.

It was a mess, the mains transformer was shot, the output stages needed rebuilding and everything else needed cleaning up.

There is a capacitor between what seems like the anode of the output valve ECL86 and its grid.

One of them broke, the other I removed to check.

At first I thought it was a 100pF but it seems to read 10pF on the capacitor meter.

On some diagrams, there is a capacitor between the anode of the triode section and the grid of the pentode which is 22pF.

So what should I replace said capacitor with, 10pF, 22pF or 100pF? I would assume its a 1KV or 1.5KV ceramic type.

Anyone got any thoughts on the matter?
