Up for auction is my personal well maintained and perfectly working Triplett 3444 Tube Tester. This tube tester is the best tube tester you can use. I simply rarely use it and decided to sell it.  Triplett 3444 tests at 250V/250V which is the standard to compare against in just about all tube data sheets.... This means 250V plate....250V screen.....or for triodes just 250V......Almost every tube data sheet for popular tubes will use this 250V/250V for testing conditions.... gm testing is typically done with the tube in Class A and for 6L6, EL34...ect....250V is close to max operating for class A.... The Triplett 3444 is better for straight gm testing since the meter will give you direct gm reading. Shipping will be a flat $55.00 to 48 States. Please check out my other auctions.
