I think @Dave Olson is your best source to find answers. I know Dave has mentioned the new CW-80 before on the forum I do t remember what thread I’d have to go searching but I do remember some.
from what I recall it is very close to the new PH180 power supply so it will no longer need the cheep fan that makes a lot of noise. And it will also be UL approved (if I recall correctly) so I’m sure there a LOT of little things we might never think is necessary that UL will require
