And another very dumb question. Is there any chance the 6AB4 and 6J6 coulda got interchanged; that is, the 6AB4 in the 6J6 socket?
I thought of this and doubled checked to make sure the 6J6 and 6AB4 were in the correct tube sockets. According to the SAMS and original DuMont paperwork they appear to be in the correct sockets.
