Etapa de Potencia Parasound A21

Vendo etapa de potencia Parasound Halo A21 muy cuidada y en *perfecto estado estético y funcional, la vendo por pasarme a las válvulas, poco hay que decir de esta etapa que no se sepa ya, calidad y potencia para mover con solvencia gran parte de las cajas que hay en el mercado.
Precio 1350€ envío incluido pero prefiero que pasen a recogerla dado su peso de 30kg y para probarla, no dispongo que embalaje original pero la embalaría para que no sufriera ningún desperfecto.
