Hell yes.  When I built my tube LFO (like your phase-shift oscillator
design from long ago, only using a dual pot to control the frequency
to get more range), I put the 6AF6-G eye tube in like you did, and
people loved to watch it even though the LFO wasn't even controlling
anything.  And sadly, still isn't; I had kids and got a "real job" and
haven't had time for the tubes.  Maybe in a few years.
