Nadie sabe nada de estos equipitos?

quitando que reparé uno de un chico de Bilbao, las entradas de audio y sonaba realmente bien, no se que decirte... es un buen ampli

Para mi gusto, mejor el ampli que las cajas.

Creo que ese amplificador con unas cajas de algo más de nivel, subiría varios enteros.
