So, a simple question - what amp will members in the draw be using these parts in. Or maybe Mr. Pass has some suggestions for us.

Are they drop in replacements for the Mosfets in some of the FW designs that are currently being discussed in the Pass Labs forum?

 

[baeijsman]

I'm pretty sure I read somewhere that Pa had something in the pipeline specifically for these.

 

[gary s]

I had a quick look around some of the threads but missed that - lets see what transpires.

He have talked about a diy project with laterals here : https://www.diyaudio.com/community/threads/f5-power-amplifier.121228/page-834

The lateral parts have lower transconductance but also lower temperature coefficients.

I do have a diy version using the Alfet laterals, scheduled for release this year.

Maybe we are not that far from a diy F7

I have PC boards for an F5L, similar to F5M, but needless to say, more expensive...

Me likey F5L version

 

[e_fortier]

Hi Vunce…can you share what the F5L is about..

 

[Vunce]

Just heard about it 8mins ago from Mr Pass.
But, I seem to like LatFet amps.

 

[e_fortier]

Ah ok, makes sense 😀

Will this turn into a project for the Alfet giveaway?

Nelson, when you say more expensive - can you expand on that comment thanks.

 

[Vunce]

Just a guess, but probably because the output devises cost more than vertical mosfets.

Many thanks to jugi63 for the "give away" and his organization and many thanks too to Mr. Pass for his generosity.

Well that is certainly correct Vunce, then he made that comment before giving away 60 quads!!

So maybe not more expensive for 60 members around here.

Now to get hold of the pcb (gerbers) - any hints Mr Pass at this stage, or too early to ask?
