Brand-new, authentic NOS BVA Mullards ALL do this for a while 'til they're broken in a bit. Perfectly normal for these outstanding toobs.

btw, I am curious to how "tube break-in" affects the flash?

I have a Zenith branded amperex made in holland that flashes at startup. It's not new but sounds great. very mellow in my setup. I would like to find more but haven't.
