3 VINTAGE CUNNINGHAM CX-301-A "GOLD LETTER" TUBES, EXC!
These three vintage Cunningham CX-301-A tubes are in excellent condition . Tested on a vintage Hickok 532 tube tester, they all tested at 1350, 1200, 1150 for GM (mutual conductance). The average GM value for an 01A is 750, so they test above average, and well above center on the English "GOOD" scale. Interesting that the lettering is in gold, making them a bit unusual. Sold as-is since I have no control of them after shipping, but check my feedback if that is a concern (I have sold a lot of tubes recently with all happy buyers). Check out the other tubes listed this week. I will combine items to save on shipping.
