[NJARC] tube testing

[Scott Roberts]

Steve- Here is the schematic(in .deju format- if you
need, I can send a link fot the viewer, but it is on
the BAMA site) for a model 612 Precision tube
tester...

Easier just to buy one, and have it around... Mine is
my favorite toy: it has a multi meter, and does all
sorts of neat things besides just checking tubes! :)

Still fighing the 37-650 battle: I have the RF
subchassis out again to recheck wafer switches and BC
RF coils...

"War is an ugly thing, but not the ugliest of things; the decayed and degraded state of moral and patriotic feelings that thinks nothing is worth war is much worse. A man who has nothing for which he is willing to fight, nothing he cares about more than his own personal safety, is a miserable creature who has no chance of being free, unless made and kept so by the exertions of better men than himself." John Stuart Mill, 'The Contest in America', Feb. 1862
