Anyone wanting a Rectifier or an amp with multiple types of pre and power tubes and every Rectifier setting ever, all on one amp.... need not look further. Killer amp. $1500. Thats half price of a new one. This amp has barely been played. Still has tags on it. Has 6l6 and el34's for power tubes. Has as many knobs on the back as on the front. 4 independent full tweakable channels. It is the ultimate rectifier. So much more to the amp then what i have mentioned. They sell for 3000 new.
