Yessah they do. On a side note, I don't know about Admirals, but I see that the D16 Sylvanias roast the area of the PCB under the horizontal output tube quite badly. That area on this chassis is spotless. An indicator of low hours perhaps? Most of the dust in this is light gray. I've got to get a paintbrush to clean up the chassis a bit.

Well well well, look at this 6BV11. The dust was obscuring the getter. Thanks for picking that out. That's one problem down anyway. It's an original Admiral tube.
