Hi Everyone
I will be very soon releasing a new amplifier.
Here are the features of this new design
Fully Symmetrical Double Differential Input Stage
All Hexfet Differential Input Stage
Fully Symmetrical Topology
Bipolar VAS HEXFET Cascoded Driver Stage
4 x Single or Dual Die Lateral MOSFET O/P Stage
HEXFET Constant Current Sources
700Khz Power Bandwidth
Very low Noise and Distortion
Compact PCB measures only 100mm x 50mm
Specifications
150 Watts RMS into 8 Ohms
280 Watts RMS into 4 Ohms
Frequency Response: 10hz to 700khz -3dB
SNR and Distortion: To Be Announced
With Dual Die Mosfets Power output can be increased to about double
The quoted power.

Hi Peranders
Not sure why aussieamplifiers.com is showing my old web site
but you need to goto www.aussieamplifiers.com
Very strange I will have to ask my web site host where on earth
is this old frontpage comming from, it doesn't show anything by the way.
Very strange.......
I will have conceptual schematic on my website soon.

www.aussie is pointing to an IP number and .aussie to an another. Normally you have www.url.com and url.com pointing to the same IP number.
This was only as info. 🙂
Will you create nice looking doublesided pcb's also?

I know, but what doesn't make sense is why I am paying for two static IPs
My host is a friend of mine so I will give him a call tomorrow.
Its rather funny really I was in the IT industry for the best part of
15 years and I have not seen this before.
Thanks mate...

How a HEXFET thing could be called symmetrical? N-ch and P-ch MOSFETs are anything but symmetrical.
Also, which are the advantages of MOSFET current sources? I'ts a well known fact that MOSFETs suffer from higher cpacitances than bipolar devices, that become extremely non-linear when Vds is below 20V to make things worse.

Oh, that's the point of view of somebody that is tired of dealing with HEXFETs in switching circuits everyday 🙂
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.

An externally hosted image should be here but it was not working when we last tested it.
Link: http://www.aussieamplifiers.com/av100.htmThe 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.
Hello Tasmanian Tiger
Hi Anthony E. Holton,
Congratulations on your New Creation of Symmetrical Balanced Mosfet amp....This would be a great contribution to DIY forum and I really believe that all members would appriciate your work,...Keep it up........we all are waiting to taste your recipe of new amp......😉
Cheers mate,

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.

Thanks guys for your comments.🙂
I will be releasing a Vertical O/P Version also...
More to come...

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...

I hear you. I've got much much too much up close experience with HEXFETs, IR, and their founders...ooops is this thing on?
