Predictably, D603 was the culprit. strange, because I had actually replaced that diode a few weeks back - purely because it looked bad.
This has fixed the problem of the final drive dial pegging hard left, and the problem of the anode starting to glow after a few seconds of tx.

However still not much RF coming out of the PA. Hmmm.
