Elevata potenza d’uscita ( 50 + 50 W RMS) e dimensioni contenute sono le caratteristiche che contraddistinguono il GRAAFiti 5050.  Il circuito è un tipico push-pull in classe AB. Lo stadio di potenza utilizza i  tubi KT88A particolarmente adatti ed efficaci anche con carichi difficili e trasformatori d’uscita realizzati a mano, da esperti artigiani, con l’impiego dei materiali migliori in esclusiva per GRAAF. Il GRAAFiti 5050 è dotato di un nuovo bias control, caratterizzato da una circuitazione a polarizzazione automatica, che permette di ottenere bassi livelli di distorsione. In tal modo si assicura alta stabilità alle variazioni della tensione di rete e ciò non rende necessaria la messa a punto dell’amplificatore anche in caso di sostituzione delle valvole di potenza. Nella sezione di guadagno del 5050 vengono utilizzati due doppi triodi 6922 scelti e selezionati per la loro linearità e l’eccellente rapporto segnale/rumore. I componenti della linea GRAAFiti sono stati tutti assemblati a mano con la stessa cura e precisione che già da tempo contraddistingue i prodotti GRAAF.
