Another marketing gimmick?


Put micro sized components in a glass structure that resembles a vacuum tube?

Im thinking pure aesthetics were the goal here. No need to put those "advances" mosfets in a glass tube?

I guess someone will buy it.

A friend of mine was the youngest engineer at JPL at the time and he worked with Gallium nitride back then. That was in the late '70s. I don't know what the application was but he told me it was difficult and dangerous to work with.

Nope. My intention was not to look knowledgeable at all. You must not think that others do things for the same reasons you do.

As for personal attacks, you just mask them (sometimes poorly) in your rebuttals, but they do show. As for mine, it's just snark, making it easy to digest, and out in the open.

Using "radar" and providing the link with the attribution shows I was just lazy. Nothing more.

Your needling every and any point to better others shows you to be an audio (and carpet) harpy of the highest order. I think you’ve found your niche.

Carry on.

The device I use was developed very specifically for class D audio, not for power supplies, low voltage points of load or RF circuits.
Yes, others use GaN devices but not the ones he worked on with the supplier and he bought out all the inventory. I don't know where you got the notion that the circuit is obsolete unless it was meant to demean. 

He's devising a new one to deal with the increased power of his next amp. Going back down in power doesn't appear to involve modifications. That, and although other makes use some form of GaN device, they're not intended for audio, like his are.

And, yes, I took some poetic license in saying that it was for radar as I was lazy to not list all the other applications. You're quite the pill, aren't you?

@jond ,
That was just a bit of snark what with all the dog piling going on.
Nothing personal.

OMG, you guys are becoming a cult.

That's just an aesthetic take on a what reviewers say is a great sounding amp. It's a Gallium nitride power FET device that only the maker has access to, since he designed it. All other GaN devices are for radar and if used for audio, are modified or backward engineered. It replaces silicon devices as it's way faster.

Here's a review of it: https://6moons.com/audioreview_articles/agdproductions/

The reason he put it in a tube is, wait for it, he's somewhat an artist as well as an engineer.

All the best,
