they are literally silver-soldered together, so they may - if required -
be disassembled, repaired, and re-soldered. However, most worn out
ceramic-metal tubes only need to be re-carburized with acetylene gas and
re-pumped to restore full function for c. another 20k hours of operation.
Can the 3CX800A7 be rebuilt? I am happy with my Alpha 86, but the
thought of eventually needing to replace the tubes at current prices is
scary.
