Thank you for your inputs, from various previous measurements I think the answer to A & B most likely is No, but would not discount anything at this stage.

I will certainly check out the transformer as you suggest but in-situ, especially as early on I found out that the primary winding wire colours were somewhat different to the schematic, although at the time resistance checks of the primary winding taps made sense even though some of the wire colours were different.

I am also bearing in mind that from day 1 after replacing the 50uF dual can reservoir/filter capacitor (that had little capacitance resulting in very high mains ripple) the HT voltage has apparently been high (compared to schematic values) and also the output winding voltage, even more recently when measured using Avo.
