Thanks Mike and Lawrence for the helpful feedback.

I had trouble relating the schematic on page 8 with the View Under Chassis on page 9 of the KB Museum service manual - realised that not all components are shown on page 9.

Had a long hard look at the circuitry around V2 and what I have in my set. To assist myself I've highlighted in RED in the schematic below the capacitors and resistors in the vicinity of V2.
