[AMPS] Impedance of amplifiers

[Tom Rauch]

If the impedance of amplifiers is a "low one or high one", as 
credited to professor Areby?:?, then you could prove it with this 
simple test.

Put various resistor on the output, and measure the power 
delivered. If the PA delivers increasing power as the resistance is 
decreased, it is indeed a "low one".

If it delivers increasing power if the load is made higher, it is indeed 
a "high one".

My money is on the table that maximum power will occur near 50 
ohms in an amp designed to drive 50 ohms near rated output.

That's a simple test that separates the bologna from the truth.
