I also wonder if *all* buyers of valve power amps knowingly do so on
the basis that the output values are 'consumables' and might need
replacing in as little as just over 90 days. (And by implication,
replaced again on such a routine short timescale.) No doubt savvy ones
do. But do *all* of them ?... The issue is complicated because some
makers may soup up the stress on the valves more than others. So it
may not be clear to the buyer what kind of life to expect for that
particular amp design.

Last valve amps I had were Quad II. They certainly didn't need new
output valves every three months - and neither did the hundreds of valve
power amps the BBC used at the same time either. No one in their right
mind would build such a device. Or certainly not for commercial sales.

That's what I'd tend to expect from decent makers and designers. And why
I'm a bit puzzled by the idea that it is routine to sell valve power amps
on the basis that the output values aren't covered by the general warranty,
just a "90 days of wear and tear". I doubt saying that would stand up in a
UK court, but I don't know of any cases.

That said, I have no idea what other makers may get up to. Nor what other
countries would do with such a term for consumer retail sale of such
consumer equipment.
