I know it's not the question you asked, but you can probably replace that with something more modern very easily. Check pawn shops, estate sales, auctions, thrift shops, etc. You can also try dumpster diving around colleges when people move out in May.
Given that the largest CRT ever made was 42", and you obviously have something smaller, it shouldn't be hard to find a suitable replacement. LCDs have been the standard for about 20 years now. Plenty of old stock that people are upgrading from.
