100watt amplifier

Mile;
I would change the 220 ohm resistor on the VAS current source to 100 ohms - as it is, the VAS will have insufficient drive capability for the outputs.
Then again, this is a band-width restricted amplifier, so terrible high-frequency distortion may not ba an issue... 8-0

So heres an "improved?" version of the citation 12 using high voltage transistors:

I agree VAS resistor must be 100R with 2 pair outputs, why do you think this is a band-width restricted amplifier?

It amuses me to see the same questions appearing all the time.

What do you think of this design? Each time this question is asked you can bet that the answers that follows are the same advice as a zillion times before.

Is the search facility is used by anybody?
