And here I was thinking this was a troll......

Tell me, how can any charge storage device (capacitor) or aquadag
coating on a tube retain a charge when not having been powered up for
4 years? Must be some magic new dielectric I haven't heard about, or
the air is awfully dry.

Personally, I wouldn't bother about charged capacitors causing
problems after a week of not having been powered up, but I would still
short the aquadag coating on the tube just to be sure. After 2 weeks I
wouldn't even bother about that.

If you were referring to me as a troll, I really hope I didn't come
across as that way. I was looking for serious advice.
