p.s. probably you can find online some similar calculators, but no one has got as many tubes as this one, no one has got the accuracy of this one and THE MOST IMPORTANT THING IS no one of them you can take with you everywhere and use it where theres no internet connection, and no one has got so many different tubes on its tube calculation list !!!
