Is D for Dry? Class D...

And the above post means what? That he was thinking literally outside the box?

What's the issue with tube pins? I own 70+ year old Western Electric Amps and 300B tubes and have never had issues with tube pins, sure sockets can get loose but that's a one minute fix and tube pins are easy to clean.

What AGD has done is brilliant on more than one level.

See that what I mean, absolutely no idea.
Your not pumping any where near 400w and the current you would with a 300b just 🤣

I said it before you have no idea, and whatever your getting for this shilling, he needs to take it all back because your hopeless at it..

OK Sunshine.

No not brilliant, more inept, but guarantees return service work in the future (maybe not so stupid.$$)
There’s a HUGE!! difference in output wattage and current going through the tube pins, compared to a 10w SE 300B even a push/pull one . (do your homework) 
Especially if the AGD is "trying" to drive Wilson speakers with low bass impedances.
You may as well have those nasty spring clip speaker terminals on the back of the AGD, because that’s just as good as the tube pins and the speakers are hooked through those to the GaN output stage in the 6550 tube envelop.
