[VHFcontesting] HI-SPEC 1.2ghz amp Info needed!

[Dexter McIntyre W4DEX]

Kevin,
 
Original spec sheet:

http://w4dex.com/manuals/23cm/hi-spec/

Over 20 years ago I initially used 2C39s in the amp but later changed to 
7289.  I got all the parts necessary for water cooling but never 
completed the project.  I'm still use air cooling with an old microwave 
oven blower.  Lot's of noise but amp is stable and maintenance free.

73,
Dex

Anyway, my question is this, Does anyone have any experience with the HI-SPEC 23G2B Cavity Amp? I obtained one and I am looking to get it going. What model Tubes does it use? I was given 14 tubes with the amp, but I don't see any #'s on them. Mind you all of the tubes have been setup for water cooling so they have a copper hood on them. Any help would be appreciated. My google search proved little help.
