Some history on Tubes. 3 main elements of a Tube! Readers digest of how a tube works. Triode vs. Pentode Then, key parts of the amp – Pre, Power, Output Transformer. Address the myth of the power tubes – it is by far NOT the major thing that affects the tone of your amplifier (least important of the significant components of the amp). Debunk the marketing machine – REAL information coming to you directly from a tube amp manufacturer. Tech tips from Jason Hook from 5FDP … pay particular position of the first position pre-amp tube! A well placed, high grade V1 can make a good sound of your amp. What tube is a good high grade tube? Chinese good. Russian perhaps not the best choice for the 1st position. Tube Types: preamp, power tubes, 4 major categories : el34 (6ca7), 6l6 (5881), el84, 6550, 6V6 is a baby 6L6. Factories & Rebrands : 1 Sino China (Sichuan China) 2 JJ Factory (in Slavic Republic) 3 Reflektor Factory (in Russia), owned by New Sensor Corp in the USA (New Sensor is also known as Electro-Harmonix) Ruby, Svetlana, ElectroHarmonix, Mullard, Tungsol, Sovtek, Winged C, TubeAmpDoctor (TAD), PM, JJ, Groove Tubes, ARS – all ‘Rebranders’. Rebranders, and understanding in what they do : you are NOT buying ‘their’ tube, you are only buying their quality control! OEM has approx 50% failure rate (worth more to a company to have a lower failure rate). ReTubing : When and how frequently should you retube? Diagnosing Tube Problems.
