Offered here is a precision-matched pair of vintage RCA 6V6GTG beam power tetrodes, featuring the iconic Black Coated Glass and Black Plate construction. These American-made icons are the definitive choice for the rich midrange and sweet harmonic compression sought by audiophiles and guitarists alike.

Both tubes have been thoroughly analyzed on the Amplitrex AT1000 digital tester. Following our Percentage Method, the results below show how each tube performs relative to the 100% factory design-center specifications for this tube type (Ip = 45.0mA / Gm = 4100 µMhos).
