β24: A discrete, cascoded, fully-differential power amplifier

Featured Replies

This one is for all you speaker guys. I figured that most of you don't venture over the Headwize very often and honestly, this thing is so freakin' over the top that I just had to post it here. This amp will debut at the Norcal meet this weekend and holy heck I wish I could be there to see it.

And hopefully Ti won't mind if I link to just a few of his images in this thread. Honestly, it's one of the most impressive builds that I've ever seen.

That's going to be a long one. Hope you can get it in the mail for the meet k thx

It looks better than most commercial amps. I was tracking Ti's progress for awhile, but kind of forgot recently. I just thought it looked so damn cool.

I wonder what the parts cost is on that thing.

I believe someone on the DIY thread on HF bareboned it at $1200. Ti's proto with its really nice chassis and I believe he went overboard on some parts probably exceeds that easily.

Paging penguin, paging penguin.

I want it to match my beta22. Thx. :o

That's a beauty. I'm looking forward to hearing reports from NorCal. Nate is it too late to cancel my 8 case quadrupled menace and switch to this? If it is too late, no problem.

The new custom title sure beats "Spammer". Thanks!

Jack, in all seriousness if anyone asked me to build this thing for them they'd better be prepared for price tag in the high four figures (decimal points need not apply). It is massively complicated, has an extremely high parts density (easy to frack up) and absolutely requires a tank of a chassis.

<asshat>yawn, build a real Nelson Pass design, not some random copycat</asshat>

Care to elaborate?

He's saying the balancing scheme in the b24 follows a nelson pass patent. It's an overarching patent tho. I think this design is fairly unique.

Ah yes now I remember all that drama.

Care to elaborate?

well, the patent in question is "super-symmetry" and there's a lot of ink spilled on it. amb did the right thing and got permission from Nelson and all is good in the hood. I was just being snarky / a NP-fanboy.

If I had the cashola I'd shell out for an X1000.5. That's bragging rights right there.

Spendy! :o
