Has anyone used a GU-81M in a homebrew linear? I like the idea of
building a quiet linear and this tube looks like it should do the job.

I've found very little info via google apart from a few wildly different
specifications.

May be google translator will help you.
This PA can work also with one tube.

This is "hard to kill" tube ;-) - very good to use in club station
(idiot proof).

Many thanks, that gives me enough info to get me started. I plan on
using it for RTTY contests, I have an amp using the 4cx800 but the
blower gets to me after a few hours. With the price of 3-500Z in my
main amp getting silly this looks like the ideal cheap tube to use with
the PSU from the 4cx800 (2800V), just bought two of them on ebay for $60
the pair + one socket. I probably wont need the spare as he's had 12
years of contesting out of a pair.
