Default Amplifier issues

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.
