FYI - plug for this particular book. It discusses some rather
interesting design principles, and observations about testing tubes,
how
they don't always perform the same depending on the circuit, etc. and
how to extend tube life, yotta yotta yotta.
long read, good info. mostly skimming, had a copy as PDF for a while
now, looking over it again for ideas.

I'll have to see if I can get the GE tube book [I've got one, but it's
old, worn, pages falling out, cover missing, etc.].
it's titled "GE Receiving Tube Manual". don't know when printed,
probably the 60's. It was kinda old when someone gave it to me in the
mid 70's. Has "RC-27" on the binding. Over 600 pages. (only page 1
and the front cover seem to be missing, probably not important)
