Good Point, Mark:
The simple fact is that some amplifiers are built with almost the same
components that were used in the 100 watt transceivers. Bandswitches,
parasitic suppressors, and even tank coils in some amplifiers are not
significantly larger than in the old tube drivers.
There is a practical problem in the design of amplifiers, however, since the
components of the amplifier (in a properly designed amplifier) are larger.
This means that the spacing between components increases - which leads to
greater stray inductance and capacitance. This may be a significant cause
of problems for high powered amplifier design and construction.
Some of the newer amplifier tubes use lower voltages - which permits closer
spacings and lower stray inductance and capacitance.
