[Moon-net] ALL: Burn in a filament

[Dominique Fässler / HB9BBD]

Hi kim
I fully agree with you to do this burning in. I usually let them on for
24hrs, - though I have no 4cx1000 but some Thomson TH327 and other series.
It definitely pays off to clean the clima within the tube. The getter will
pick up all the pollution molecules which sail within the tube. 
I then go for some RF and usually the tube is safe.

HI gang

I need some experience :

have set  up  a 4CX1000 with only filament ON, and have slowly raised  ( 
over a few hours) the votage up to
the normally used ie. 5.8 V  measured at the socket.

How long time is  nessary  for achieving the " normal max vacuum"  again  ??


I think this has is of  general interest , so PSE answer via the net (direct

is OK as well TOO.
