the harmonic spectrum of the 6P5GT - nice!

Now that's impressive. I want to try one now! Those are nice plots.

I have a few amongst my collection of 6J5 types, and they are indeed very
neutral sounding. A very nice valve. Hard to get these days, and creeping up
from £10 to £20 and beyond. Triodes like this and the 6J5G types like CV1932
are vanishing into the hands of collectors. Fortunately the 7193 (2C22) is
plentiful, and it's arguably the best of the lot - extremely clear and
detailed. Be prepared for two top caps!
