Hello to everyone. I Hope someone could help me with one doubt. I was thinking on buying a Pioneer Amplifier SA-710 (130 watts), the only thing stopping me is this, the owner says the he changed the output transistors of one channel for some random one, not an original component. - Amplificador Pioneer Sa-710 Clásico Vintage - S/. 350,00 en MercadoLibre So comparing that with a Technics Amplifier New Class A (150 watts), that works fine, but has a not-so-great look. - Amplificador Technics New Class A - S/. 400,00 en MercadoLibre What would you recommend? The price range are very close, both are about S/.400 Soles which is something around US$ 160.
