Includes one used Sylvania made for Baldwin organs 12AX7 (at over 120% of minimum new spec and not microphonic), one used Sylvania black plate with smoked glass 6V6GTA (at 101% of new spec and not microphonic), and one used Sylvania black plate 5Y3GT rectifier (at about 87% of new spec which is still considered a strong reading). All were made in the USA and all were tested on my calibrated TV-7. And I tested them all in an amp together and they sound great. Guaranteed good. Returns accepted.
