Update on Pa's new F5?

[Zen Mod]

I have at least 2 iterations of that**, even with complete pcb files ...... but, Bubba ........ that's so loooooow on my to-do-list

**just two trimpots per channel - one for Iq, second for THD Spectra

amp by concept being Berserker per se, do not expect me just publishing schematic ......... just to later need to help in development process, having ready fire extinguisher

Could it be a DEF F5? Maybe without the F.

 

[Tea-Bag]

Is this even going to be a published diy schematic or a commercial endeavor? If the later, best wishes.

 

[tnolan]

I should go ahead with an F5T build anyway, uh...right?

 

[Nelson Pass]

I have the boards, just need to get a couple other things out the door.

Should have built that time machine back when I was still smart.

Audio amplification is somewhat safer. You don’t want to mess with those Daleks.

 

[Zen Mod]

Daleks are tricky

Speaking of Time Travel... I'm re-reading William Gibson's "The Peripheral" - a fascinating
twist on Time Travel. Highly Recommended.

I'm also finishing up my Zen V5 build... the stripped down essence of the F5. A project
i've been working on and OFF again since '05... !!! talk about a long wait 🙂

Never safe to approach their plungers 😀

It's going to look like an F5. Just some interesting twists.

Are you referring to the external appearance or internal?

I wonder if some variation on this topology would work:

 

[dantwomey]

I have the PS, chassis, and Daleks ready. I should have mine running an hour after Pa releases the boards! 😱

 

[Nelson Pass]

I wonder if some variation on this topology would work:

You already know the answer is yes.

Such a beautiful circuit. Excited to see the twist…

Great idea.
I wonder if you have to tailor it to the speaker though.

Very quick and dirty; not optimised.
But the effect is clearly visible.

Very clever.

and , if amp is single rail, there are few more tricks .....

I was trying to eliminate the degeneration of the output FETs. Here is another way that we have seen before.

Your last solution does not have the clever thing that the first one has.
I think you don't realise why I said it was clever.
You can see I still have the source resistor in my Spice files.
