I have a 41-290 that I am restoring for someone.  I am in the process of testing all the tubes in the unit.  I have come across a problem with the type 37, 41 and 84 tubes in this unit.  I am unable to test them in my Sencore TC28 Hybrider or B&K 747B testers.  There is no socket that fits these tube.

How can I test these tubes so I know they are good/bad?  Is there an adapter socket out there?  Any help/knowledge is appreciated.
