Same tube in this case Steve, but better testing.
Be sure to add a grid over-current protection circuit to your amp. If
it does not have one, or you will eat up the new tubes.
A fuse is NOT enough, nor is a warning light. You need something that
quickly knocks the Titan off line if the Ig ever gets over 50 or 100
mA... even for a brief instant.
