My aim with this app was to make the datasheets that we usually use in pdf format available in a modern app, with a real time load line representation, so that people can understand how tubes work, and how you have several angles of action possible. Not having to google for the nth time the name of a tube + datasheet is already a relief for me haha! You'll find also pinout + heaters information for the selected tube. I added all the information by hand to be sure that all the basics are sure, proven and solid. This app will be a continued developpement, this is its first iteration. In the future, i would love to be able to share other users settings in the future, so we could follow people's taste if they posted different settings for the different tubes.. And it would remain eternally for other people, just like schematics from the 40s! I will do my best to add more tube models also. Your feedback is more than welcome as this app is meant to be useful to the diy tubes / pro audio community as a whole! The current tube models are: EF86/EF806S 12AX7 12AT7 12AU7 12AV7 12AY7 6CG7 6SJ7 6SN7GT 6J5 6J7 6DJ8/ECC88 EF800, EF80, E80F E180F EF184 6N1P 6N3P 6N16B 6V6GT EL84 6L6 EL34 6550 KT66 KT88 300B 2A3
