Often this is a symptom of overload, usually a case of either the LOAD drawing LESS than design current, or the series resistor going down in value.
Usually worse at startup, because B+ is high due to little or no load from other tubes.

"Chuck Grandgent" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- I'd noticed my OB2 in my R4A starting to flash or flicker bright orange, maybe a little reddish tint. First only at startup, then more and more. So I got a "new" OB2 and now have only a continuous orange glow from the base area, without any flickering. What precisely are the failure modes of these regulator tubes ? Chuck, K1OM
