Hornlover,
Do not tell Leo Fender that you cannot overdrive a tube amp more gradually to clipping without immediate and catastrophic consequences. He made distortion a thing of beauty. He'll have to take back 50 years of effort.
A clipped wave, when totally flat-topped, allows the amplifier to pass the peak output, rather than the normal average of the peaks. The clipped wave, like DC, also results in an immediate transfer of heat to the structure of the driver rather than output. A compression driver/tweeter of high efficiency has far less mass to dissipate heat,
does not work well as a light bulb, and fails.A transistor amp has no other option but to flat top the wave. Its operation goes from full output to gross distortion with very little middle ground, once the output capabilities of the power supply and voltage rails are exceeded.
