The Electro King is an idealized recreation of the classic McCarty era GA-40. Its circa 1957 circuit features two cathode biased 6V6s for 15watts of recording and small club power. The heart and soul of the Electro King is its 5879 preamp circuit; a single NOS 5879 input pentode for each of the normal and tremolo channels provides rich distortion and natural tube compression at any volume setting. Notes seem to be “blown” out of the amp with overdriven tones that are saturated, dynamic and musical. The Electro King is singularly suited to slide guitar styles with its expressive open tones. True to the original, the tremolo is accomplished with the aid of an NOS 6SQ7 oscillator tube and is a driver modulated volume style tremolo. Slim Harpo/Lonesome Sundown spoken here. The Electro King is fitted with a Jensen P12Q alnico speaker for true vintage tone. New Victoria “Radio-lectric” logo and two tone tolex covering standard.
