"John Larkin"


It's actually not a bad idea to have an opamp per output transistor,
if you do it right, which this guy clearly hasn't. I make a power amp
that uses 32 300-watt fets in the output (16 p-ch, 16 n-ch, +-200 volt
rails) and do just that. It forces essentially perfect current
sharing, nukes the device tc and part-part variations, and makes lots
of gate drive available.



** What fets are P ch, 300 watts and 400 volts ??

Is a bank loan needed to pay for them ??
