If it's an amp for home use and isn't going to get that much playing time (like a lot of really old amps), the power tubes will last a good long while. If you've got a pair of RCA black plates (or whatever) that you really want to use, then why not? I doubt I would do it, but then again, I can usually find a matched pair in a box somewhere...
