[AMPS] interesting SS amps

[George K. Watson]

>> As soon as devices are developed that can run directly off of rectified
line voltage (and
>>they're getting close)

YES! They may in fact, be here.

>> , power supplies for these will be cheap and very light weight.

Very much here. The power supply issue is probably possible to address at
the 50V drain level,
but I can't say for sure as I am a novice at buck converter design. Anybody?

>>Very high efficiency is also possible with envelope
elimination/restoration techniques and the like.

Or stick to CW/Digital.


>> Solid state devices also outlast tubes.
OOPS! I would say that they have the potential to outlast tubes. This
potential is only
realizable with very good design. Most SS amp engineers that I have spoken
to have quite
a bit bag of BeO packages filled with impure slagged beach sand.
