With attention paid to most details, a SET is very reliable.
I've experienced a SET failure that was built from an arrogant and incompetent guy, who sold many incompetently built products to "screwed" customers. I've repaired and modified an amplifier (6N6P-6B4G-5Z3S) built by him and I've seen many things asking for trouble:
-putting 50uF after a rectifier rated for 20uF. The rectifier was of course.. arcing. There were no damping resistors.
-The output tube was 50% above datasheet mentioned power dissipation.
-The amp was self-oscillating, too bad I don't keep the photo with the wire dressing and the grounding.
-The diodes for the heater were underrated and there were cases of shorted rectifiers, leading to the feeding the tantalum filtering capacitors with an inverse half wave. I personally experienced an explosion of a tantalum capacitor K52-2 in such a amplifier, it goes off like a gun - a scary experience.
The problem isn't much in the technology, but in the builder himself.
