Hi Carl:

The VT-127A is a good tube. It was a repackaged Eimac 100TL for radar use.
Just more filament current. They were cheap after the war, but got
sidetracked because the 304TL was also cheap and ran more power.

Love to see a photo when you get done as I have a few sitting in storage
that belong in a rig.
