$125 shipped CONUS! Very early versions, and I believe they were the first versions of the long plate 12AU7's.
These are some very nice tubes. Very close matching pair with matching date codes!!
Long plate with dual support O getters. They also have blue paint on the tips likely indicating low noise.
Test new on my TV-7. Minimum for this tube is 1400.
2300/2400
2400/2450
You won't get any better than these. Thanks!!
