When I fire up the Blackstar, the power valve nearest the input back glows REALLY fucking brightly before dimming and leveling with the others. Shown this here, got some spare valves to put in and try from MDV but not tried this yet. Any ideas what it could be?

I don't know enough of about valves, but that is not doing it any good at all. Not sure if it's biasing or what, but all the heaters should be coming on at the same time and you really don't want that much glow.
Assuming it isn't your accent that's done it.
