[sdiy] tube repair

[anthony]

Perhaps I should just throw it away to keep me from lamenting, but I broke a 
gold-pinned 6922 a while ago. I was really looking forward to using this as 
the first 2 preamp stages in a hi-gain, 2xEL84, 100% (or close) 10 watt amp. 
I can't remember what the make was - it got wiped off when I cleaned off 
thebasement grime that had accumulated., but I know it was "made in 
Holland", so Philips is a good candidate. Anyway, only the top gas purge nib 
and a bit of glass aroundit broke. I figured a skilled glass blower could 
fix the glass work easilly. Heck the tube even had the look of being 
hand-made by a glassblower (the way the body dipped in the middle that was 
slightly irregular). As for the getter: what do they usually use? I have a 
small lanthanum rod in a vial. I wonder if it reacts with oxygen well enough 
to "get" that last bit of O2. How do they "flash" the getter? Does it happen 
during the final joining of all of the glass parts or does the vaccuum do it 
or is it a combination of both? Is it really worthwhile to fix a broken 6922 
with gold pins, or should I just tosse the thing or make one of my little 
"Cornell" boxes out of it like I did with a broken EL84 among the other 
EL84's I found when cleaning out my basement.?

cheers,
