The repeated claims that tube amps "required that much maintenance" is a curiosity. My SS amps have run about as long as my tube amps before breaking. The thing with getting those SS amps fixed though is that more often than not the cost of repair was not much less than the value of the well used SS amp. The tube amps though tended to be worth almost what they originally cost new, and in some cases more. But WRT "going forward", I can see a time when the poor quality tube amps that are cranked out and sold to the masses are representative of "tube tone" will be the same sort of problem. Lots of modern import tube amps are just as disposable as many 10-20yo SS amps are now when the are road worn and not working. All these cheaply made tube amps with tube sockets mounted on the thin pcb boards are not going to hold and increase value, not going to be the long term reliable amps that tube amps used to be, and may never have sounded as great as those old tube amps did. There are of course plenty of top notch tube amps built now, but for the most part the amp buying public snubs high quality amps as boutique, and won't even try them, never mind buy one $1500 amp instead of two $500 amps and $500 worth of pedals. As far as new SS amps sounding better than old ones, IME there were very good sounding SS amps decades ago, with names like Peavey, Polytone, Acoustic, Gibson and Roland. What SS has greatly improved on IMO is dirt which comes in pedals as well as amps, though not as good as tube dirt, and ultra light weight. The light weight feature may be what sends me back to SS amps one day. For now there are plenty of 15-18w tube amps that are light weight and sound great for $250- $500.
