3CX400A7 / 8874

[Glen Zook]

You are thinking of the conduction cooled version, the
8873.  The 3CX400A7 / 8874 are still being
manufactured and haven't gotten to the price levels of
the 8873.  The 8874 is air cooled.

Indeed these have become quite expensive to replace.
You might look at some of the Russian surplus ceramic
tubes and modify your amp to use them. I'm in the
process of rebuilding a GLA1000 to use the Russian
GI7B tubes.
