It wouldnt hurt to run them for 20 minutes or so with the plates showing a
bit of color with no drive. The same holds with Eimacs that have been stored
for several years. Be sure a HV current limiting resistor is in the HV lead
in case a tube decides to flash over.
This assumes that you have sufficient air flow to keep the tube seals
contented. At least treat that original SB-220 fan to a tear down, cleaning
and relube.
