Question for some of you tube experts:
John Lyles post explained how gasses liberated from the plate in a tube
can produce gas arcs inside the tube and casue serious damage.
Fine and dandy. Understood.
So here's my question: Why then can one successfully operate gassy tubes
in an amp w/o them arcing. I have two 4-1000A's (sorry Carl please
pretend that they are 3-500Z's) that have a nice blue glow when keyed.
This kind of tube is called gassy. Yet I don't have arcing problems with
them.
So....why would gas cause an arc in one tube and not in another? Are
gassy tubes such as mine prone to arcing which means I better use caution?
73,
