[Heath] Gettering 572B's for a Heathkit SB-200

Hello Group,

I have a few 572B's that having been unused for unknown lengths of time,
probably several years. It is possible to getter this tubes be for putting
them into service in order to avoid arcing or flash over? Are there any
other measures that can be taken with the 572B's to avoid failures at
startup? I plan to use these tubes in an SB-200 amp. The amp is working now,
but the tubes are weak. The replacements I have are either New Old Stock or
"good" used.

Thanks and 73,

George, KC1V
