I wonder if the 4CX800's will be a direct replacement for the GU47b's? IIRC
there never really was a 4CX800, that was just a label given to the Russian
tubes since that described them in 'Eimac' terms.

Subject: [TenTec] The Titan IIII - 4cx800s
Molly at Alpha indicates that 4cx800s are becoming available again and
that Alpha will offer matched pairs in the January timeframe. She didn't
indicate a price. If they are available to Alpha I am sure they will be
to Ten Tec. I am not sure I would write off the 4cx800 based amps yet.
Now, I don't think these are current production items, but NOS Russian
sourced. Even so, those 4cx800s have been a great value to the ham
community for the last 10 years or so. They have proven super reliable
for me. Maybe a good strategy would be to pick up a spare matched set -
would probably last most of us for the rest of our lives. I do believe
you would need to swap them with your current finals to keep them from
getting gassy.
