After reading about all the troubles of rebuilding the 15GP22 I couldn't help but wonder how much a production run of say 100 would cost.....assuming that these could be made in perhaps Russia or even China.

Am sure that per unit tube cost would still be quite high, but what other options other than substitution would be available in the future? Figuring that there are 100 operational sets currently this would supply a single back-up tube for each of them. Granted, not every CT100 set owner would want one or be able to afford one, but there are some who might actually want to get several.....plus, with the tubes available some more sets may be put back into operation as well which again increases the number of tubes wanted. Just thinking out loud here. I'll shut up now.
