The AV100: Compact All Hexfet Power MOSFET Module.

This amplifier is the first from aussieamplifiers
that has Hexfets in all of the gain stages of the amplifier.

And it has N and P Channel output stage.

Not one Bipolar to be seen.


The prototype sounds absolutely liquid in the mid- range
and the bass response from 1 pair of output devices is amazing,
very tight and incredibly musical.

I have always thought that FETs are good for voltage amplification.
And bipolar makes better for amplify current.

But truth is not always simple. ( as I like to believe it is )
There are surely ways to use either FETs or BJTs for whatever purpose.

Being a bipolar fan it looks like I will have to buy and build several of the animals in all fairness to mr. Holton.

It seems like the right thing to do. Why comment before one has the chance to evaluate it?

Some are quick to judge and their judgement is based on what?

Exactly.

Hi BF,

I think you have Listened only to Bipolars...and Mosfet amps...but Lateral Mosfet amps....Not vertical Mosfet amps.....though anthony's new amp is Lateral one....I reccommend you once in a life time do listen to Vertical Mosfet amps www.ECLER.com

You might hear something different....

You are 100% correct!

This is why I am looking forward to purchasing several boards and giving them both an honest listen and a performance check.
I am looking at this with both eyes wide open.

Hey Workhorse

I didn't see the final schematic of your R2R amp
Do you reckon you could email it to me...

I should have the conceptual Schematic posted on my website in
the next day or so...

Adding output cpacitance to them is a very common practice in order to linearize the otherwise nearly exponential turn-on and turn-off transitions due to the extreme non-linearity of these switching devices.
I hear you. I've got much much too much up close experience with HEXFETs, IR, and their founders...ooops is this thing on?
