Has anyone noticed this that has 6080 Mullards?
They will flash a bright white light when first turned on?
I thought one of mine was defective when it did this but it is common with Euro tubes such as this.
I will also see a weird glow on the plate for a second or two when warming up about 10 seconds after switching it on.
I think it is pretty cool to see.
I’ll see if I can grab a quick video to share.
@Bruc3 - Watch for this when your Mullards arrive from the UK.

Many but not all European tubes will briefly flash a bright white light when they are switched on.
