I have up for auction a Vintage RCA Smoked Glass 6L6G tube in excellent condition as shown with date code V2E. The tube was tested on my Hickok 539B as strong at 4000 with 3300 being good.  Guaranteed to work well for you with no issues, no gas, no shorts.  Shipping is a fixed $6 in the US and $20 international with no reserve price and an extremely low starting bid. High bidder wins, thank you for your bids in advance and you will be pleased.
