Have checked R47 and R48 now:
R47 shows 48.1 ohms (in situ) and R48 shows 42.6 ohms
However when powered (with lamp limiter) the voltage readings are different between the two unfortunately. R47 has 0.4V across it, and R48 has 1.0V.

The audio is back- was just a loose connection on the 2 pin output connector. Still same level of hum.

Also I tried removing the PX4 valves and rechecking R45 and R46, but still get about 11.2ohms for each.
