In Reply to: 6SN7 and the VT231 designation. posted by Mechans on September 13, 2015 at 14:07:04:
The 2 types maybe the same physically but the military contract may also specify various parameters they wanted like higher reliability or matched sections, low microphonics, etc. This would mean that the milspec tube would be tested more thoroughly than civilian tubes. Extra testing would eliminate almost any dud before it reached the field. As an examply IME, i found that a NOS Sylvania VT231 displays low noise levels whereas the same style NOS Sylvania 6SN7GT is more microphonic among a batch of tubes. cheers, Dak
