well keep in mind that the tubes were designed as horizontal output

when you exceed what the ratings are and what the manual tells you.
Easy to do. The few extra watts may satisfy the mind, but does
nothing at the far end.

with that project, and learned a lot. Nowadays, I am much more conservative
in how I treat tubes...and transistors!

*** I once built a linear into an ARC-5 transmitter cabinet. It had
4 6LQ6 tubes. I bought them at Radio Shack, which had a *lifetime
guarantee*
on their tubes. I put that Radio Shack receipt in an envelope and
taped
it
to the bottom of the linear.
...And I sure did drive the carp out of those tubes :).
