I have been restoring a Philco 86 all week and
finally got it all put together and running again.

I noticed that the 80 Rect. tube has a faint
blue glow between the filaments and the plates
indicating a gassy tube.

I don't have much experience dealing with gassy
tubes. From what I've been reading online
some people run with them as long as they
are still working. Others say replace them.

I also was reading that if you leave them
on about half voltage for a couple of days
the gas may become absorbed by the getter
material.

Just wondering if anyone else here has some
words of advice?

The radio seem to work fine and I get good
B+ voltage etc...

Thanks,
