Amplificador valvular Earmax de auriculares. VENDIDO
« en: 03 de Enero de 2018, 03:46:08 pm »
Vendo amplificador valvular Earmax de auriculares. Este pequeño amplificador da un sonido fabuloso. Ha sido mi opción para un equipo pequeño y portable pero lo he utilizado muy poco. Incluyo válvulas originales y juego de válvulas NOS con muy poco uso, 2 Telefunken ECC86 y 1 Mullard CV4024 (ECC81).

Diseño OTL en clase A, con triodos ECC81 y ECC86, para amplificar auriculares de impedancia alta (+200 Ohm), Sennheiser HD600, HD650, HD800, AKG K501, etc. etc. Combinación habitual de muchos audiófilos junto con los Senn HD 6X0. Oir para creer!

Precio:  € con envio incluido. No interesado en cambios.
