Denon POA 4400A

Well I know is not an NP design but is supposed to operate in class A up to 30W (?) but after looking at internal pictures of this critter I have my doubts about that class A claim.
Thanks jotom750 I know about the place (wrong one) but not much options available.
To Extreme_Boky I did say no (****)bay prices most sellers over there live in a different world.
Thanks to all
