[Amps] rebuilding glass tubes

[R.Measures]

=F0  Econco reportedly tried rebuilding 4-1000As but it proved to=20
economically unfeasible.  The advantage of ceramic-metal tubes is that=20=

they are literally silver-soldered together, so they may - if required=20=

- be disassembled, repaired, and re-soldered.  However, most worn out=20
ceramic-metal tubes only need to be re-carburized with acetylene gas=20
and re-pumped to restore full function for c. another 20k hours of=20
operation.
