First sign of a shiller. Here some more for you to agonize over.
Interviewer: I ask Alberto Guerra , why put solid state components inside an old 6550 vacuum tube envelope, bet it’s not vacuum’ed back out and sealed again either.
"Company founder Alberto Guerra admitted that he did it largely for the sake of visual aesthetics. “Otherwise a class-D amp just looks like a box”
PS: OK he’s shown all his cards, with that statement.
AGD is just GaN based Class-D slid into a "bogus" empty 6550 tube envelope, which uses (horror) the base pins for all it’s contacts, everything has to go through them, input output power supply rails everything🤢
Just the whole gutted tube thing, stuffed with solid state, and still using all the tube pins as power/current transmitting contacts, guess in time it ensures return service work when those pins start to corrode and arc over????
