Did you check the bias on the amp after the tube swap? If the bias was set too high (under biased) it would smoke the tubes pretty quickly. Single tube push-pull Ua = 250 270 V Ug2 = 250 270 V. 6L6 is the designator for a vacuum tube introduced by Radio Corporation of America in July 1936. NOS are extremely expensive but available for those who must have the real deal. Place the tube in one of those test sockets adaptors (the type that has test pads on them so you can measure each pins voltage) and plug it into the tube tester. Please note that these operating points are not suitable for the older 6L6/6L6G/6L6GB tubes. I am not saying that you should not purchase a Hickok like a 750 or 580 at the right price and condition, however in the absence of other c. Modern production tubes don't follow the tube specifications, and they likely use the same internal components for both tubes. In a single ended amp designed conservatively for the 6V6 a 6L6 probably will work fine. com 3 1L34 2P2 1R5 1A2 2S/140G 6D6A-Q 2X2/879 2Z2P 2X3 2Z2P 3A4 2P3 4L20 4P1S 5U4 5Z3P.
