RE: Better yet, read Krell's description

Given the size of the power supply and obvious lack of heat sinks it is clearly not able to supply more than 20-30 watts Class A power. Nevermind 200 watts Class A it won't get close to that.

I once had a Sumo "The Nine" that was 60 watts Class A and used fan cooling to supplement its decent sized heat sinks. It had a 1200 VA transformer for only 60 watts.

Now I have a NAT Symbiosis, which has a power transformer that is probably heavier than the whole Vanguard. It is 100 watts Class A has 4 massive heat sinks, gets super hot and weighs about 140 lbs.

That is what it takes to make Class A...even older Krell sliding bias amps were huge.

I am of course not commenting on the sound...just the claim you made of it being Class A.
