Default Re: Valve Items - Philips/Mullard Rimlock-to-Noval Transition

B9A Novals have 9 pins with a gap for orientation. B8A Rimlocks have 8 equally spaced pins with a side pip for orientation. They are approximately the same size, and as I said above, late production Rimlocks were made without the metal or glass collar at the bottom and look very like a Noval with a side pip.
