Perfect!!!: So powerful. The only thing is you need a transformer like + 50v AND -50v, or two transformers, because you need the + and the - 50 v. Really I´m usinga 52v +- transformer. After some hours they become noisy. This is because of these small fans. The fan is pure trash, so start to loose the equilibrium just from the first moment you turn on the amplifier. The fan start to touch the alluminium dissipator, and the noise become a part of the sound circuit. So the solution is tu remove the trashy fan and to install another one (external). And voilà: a powerful perfect small power amp. Blessings from Spain,. probably the best country in the world ;-) ;-)
