I've read through most of this thread and tried searching, but was unable to find an answer to a question I had. Way earlier on, Godkin said that there were limited numbers of tubes available for this amp (as I'm sure is the case for all NOS). I'm really interested in getting a 3322, and I'm sure the investment is very worthwhile. However, I'm nervous that I will get it, and 5 years from now, be unable to find tubes for it, and essentially have a worthless amp.
So my question is: NOS aside, will there be any problem procuring tubes for this amp for years to come? Even if they're not superior like the previously mentioned tubes in this thread, could I still get new tubes for it? Are there equivalents that would work still being made, if I can't get the Svetlanas or Ulyanovsk tubes? Like I said, I'm nervous about buying an amp that will one day still be working great, but will have become useless due to a lack of available tubes. Any help would be appreciated, thanks!
