I don't need mind control. The F5 has this 200 KHz square wave.
Did I mention that the circuit has no capacitors?

Don't tease us like that!

Here we are clipping into 1 ohm at 10A

 

[SCD]

Okay so you got the stability thing sorted out.

But ten amps!!!!!!

My gosh did you design a high fidelity welding machine???

 

[GRollins]

You have heard of sonic welding, haven't you?

[SCD]

Hmmmmmm Sonic welding???
Not real sure. Is that anything like ultra sound.
I heard of a guy once that had a kidney stone and they used ultra sound to make it go away. You know belly on up to set of speakers get your gut real close put on some classic rock and roll turn it up ultra high and blast those stones to smith-er-eeeeens!
Anything like that?

Seems like an ideal amp to drive a set of OB woofers....(and maybe fullrangers as well)....

That's a real gem Nelson... I would be happy with that square wave at 20K.

Being a First Watt product and of course a Pass design should be a class A amp... but 10A @ 1 Ohm must be AB?


P.S. This is a very special product... now I understand why Nelson want it published.

This will most probably be my only opportunity to say this to Nelson Pass: Check your math (you started in 2001).

I am informed that AudioXpress with the F5 article will be in the
mail April 10, just 2 weeks away.

Should arrive at my house about a month later...must get a thorough inspection at the border. Just got the previous one.
Hey, another couple months and I'll have my 6/7th anniversary as well...

 

[Nelson Pass]

No doubt information will appear on the web as soon as people
get a copy, so I don't think you'll have to wait a month.
