No it's not! The preamp section use RARE 12J1S Chinese vacuum tube and the amp section use 2pars of A1941 & C5198 Transistor in puh pull confuration so it's a Class AB amp! Mine quit working after 5 hr, They now change the tube for RARE Chinese 6P16A, I wonder why.....Anyway quality control is none existant. Next winter I will try to get rid of the tube preamp section and build my own using easy to find vacuum tube.
