Marketing geared towards audiophiles (or clients in general) is fine, until such begins to include simple untruths. To me the objections seemed to be about misleading, i.e. talking electronic nonsense. In turn, that cannot but raise doubt concerning the gentleman's knowledge of his subject, subsequently reflecting on his designs. To me, at least, it was playing the ball, not the man.
Having used many power tubes in class A push-pull mode I seriously doubt the 40 watt claim. Using the given data 410 B+ at max of 60ma per tube that would give an input power to a pair of 49.2 watts. If there is anything in the cathodes it would reduce this value a bit. The at idle comment is curious as class A1 has constant current at all times. So to get 40 watts out the efficiency would need to be 81%. This is a figure well beyond belief. Try 50% at the very best and more likely 40%. It may be that they meant to say clas AB1. I would believe that. As it stands, I'm not gonna buy it.
Decart has been caught before. I'm pretty sure the amp is AB1, he knows it, yet purposely called it Class A vecause that makes better copy.
