I have a couple of the B&K Analysts, the older one seems to have HV problems. The newer one doesn't seem to work right either but I haven't really played with it much. I should, since its been sitting there taking up a big chunk of my bench for a couple years now! I got it from the local TV/Appliance shop when the owner retired, it had been sitting on a shelf in the back room for so long that he didn't know what it was, and neither did I at first! Up on that shelf it looked like a high-end shortwave receiver!
In general, on anything from the 50s or older I replace all the caps I can. Some, in particular, are a real pain to take apart, so why have to do it twice? Changing caps can be fun, anyway. I haven't changed many caps on 60s sets, usually I wait for a problem to arise.
Going along with what Chad said, there are a number of tube organs around. I looked at one for my insurance agent awhile back (needs a motor) & our church organ is tube type. I use a tube amp for various Lions Club events (since some creep stole the solid state amp we used to have). Right now I am working on rigging up a second amp so we can call bingo plus make announcements out on the carnival grounds. The main amp I've used is a Muzak unit, 20 or 25 watts. I have a big, bad 75 watt Muzak that I bought for 50 cents (same price I paid for the smaller one!) but this one is missing all the tubes. When I started adding them up (all industrial types) I decided to shelve it. Now I'll try an old David Bogen unit that just needs the 6L6's. Anyway, from other forums I have read that there are quite a few radio stations still running tube equipment.
Of course, the goofy things I do (like with those amps) don't count, I'm the guy sitting here in the office listening to Benny Goodman on a '42 Airline that I fixed up for a friend.
