Edit Edit. Found the reason for that, it's cooked R141 (PL36 grid feed resistor)...again. Second time it's done that. No visible signs of distress, it's just gone O/C. Finger there points to C127 drawing excessive current methinks.

Have ordered some more capacitors and yet another replacement for R141 (um..five of them actually...at this rate, I'll need them too!), and will no doubt post an update with me going ...? once they're replaced and it's behaving even more strangely. Until then though, there's not a whole lot that I can do.
