we exported $37.1B worth of vacuum tubes last year. I could be wrong but that amount seems wildly implausible. Could the category actually be "Vacuum tubes, etc." where "etc" is semiconductors?
- ams6110 15y agoThe only things I really know of that would still use vacuum tubes are esoteric high-end audiophile amplifiers, and some "old school" guitar amps (Marshall, Hiwatt, etc). Is there really that big a market? Are they used for anything else?

- stan_rogers 15y agoYou are overlooking things like magnetrons, x-ray tubes, photomultipliers, CRTs (which still have a lot of applications outside of the video display sphere), krytons and so forth. It's not all about diodes, triodes, tetrodes and pentodes.
- sliverstorm 15y agoOne of my professors told me a few years ago that tubes were still used heavily in high-power commercial radio stations. Could be dated info though.
- chrischen 15y agoI believe NORAD computers still use vacuum tubes.
