Lawrence.
Then that's odd. I carefully tested both of the resistors next to it. That in itself was very tricky as there wasn't much exposed leg to connect across but eventually the readings fitted with the schematic. I did locate the cathode bypass for certain and that's electrolytic. The anode grid capacitor appeared the same as the cathode bypass but smaller. Silver coloured. I think it's a 10 nanofarad going by memory. Although having said all that, it was kind of hard to match up and I was doing my utmost to decipher the digits on the capacitor with a light and magnifying glass.
