If your valves are running “too cold” they will last much longer but the sound will probably be very disappointing. Run them too hot and you may actually like the sound better than the suggested factory setting. But run them really hot and there is a danger of red-plating which is a real threat. Any amp that red-plates the valves must be switched off immediately. So it makes sense to ensure that your amp is running within tolerances to ensure the best performance.
