Thanks chaps. I know that's a bit of an ask Andy, so please don't rush on my behalf.

Also, here's another strange one! V101, pin 6, R185 100R. There's a 10 ohm resistor here, it certainly looks original too. For a 10 ohm it's out of tolerance anyway.

I'm wondering why it's there instead of 100R. I wonder if it's because the unit is built with this resistor at the junction before capacitor C111, rather than after C111 as designed (at the R108 and C12 junction).

Any thoughts?
