Default Next Gen Amplifier from Aussieamplifiers

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, care to show anything?

Notice that http://aussieamplifiers.com/ leads to your old website.

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?

Thanks peranders

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...

I'm using www.b-one.net Excellent "product" for 1.5 USD a month and 500 MB

A hint: Avoid writing your email address correctly => spam.

Hint 2: Use one unique email address for your webpages which you can change easily and use an another for normal correspondence.

Hint 3: If you of some reason must write your email don't use the @ but a (at) instead. You can also misspell the address a bit like user@domain_remove_this_.com

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.
