[Amps] Gettering the GU-74B

[Peter Junker <dg6man@pjconsult.de>]

Dear Fellows,

What is the best procedure to getter a NOS GU-74B.

A befriended OM brought me his fairly new ZZ 750 PA with a failure of
the Zener diodes for the screen voltage.

To get this "Kalashnikov" like technology a bit more refined, I will insert
a G3SEK Tetrode Board.

But it is also interesting how to get this tube properly gettered, in order to
avoid arcing to the best possible.

In a German forum it came to my attention that the GU-74B can be very nasty
with regard to arcing.
