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
