Anyone who has a sizeable investment in vacuum tubes or vacuum tube hi-fi equipment owes it to themselves to have a good tube tester on hand to periodically check the tubes they are using. Harries is believed to have been the first engineer to discover the "critical distance" effect, which maximized the efficiency of a power tetrode, by positioning its anode at a distance which is a specific multiple of the screen grid-cathode distance. Considering the 68V zener, I can count on 70 mA of anodic current, that is enough for a 8W class A amplifier stadium. Near equivalent: 6L6, 6L6GT, 6L6GC and 5881. The Classic VT has a full solid state (op-amp based) preamp and then uses transistors for the phase splitter before the push pull 6L6 output stage. 6L6/5881 tubes More than 70 years in production 6L6 is the designator for a vacuum tube introduced by Radio Corporation of America in July 1936. Call for details. Sovtek also markets 5U4G, 5Y3GT, 6SN7, 6SL7, two 12AX7s and a few other types made at other factories. Radio tubes are valves. 9A of current. This is a great replacement for GZ34 & 5AR4 tubes. Of course, I will put all in a box and connect it to the 6L6 sockets, cause it is impossible to me to put all the components in an adapter like Yellow Jacket does. The theoretical maximum efficiency of a class A amplifier is 50% but in practice the figure would be nearer 25%. 7591's were more expensive too and usually used when clearance was an issue in the amplifier chassis. On a sonic scale, the 6CA7 tube is a hybrid between EL34 and 6L6 tube. At any given instant, even with AC heating, there is a potential gradient along the filament (except of course for the moment when the filament voltage passes through zero). That's it for the signal path, now let's examine the amp's power supply shown at the bottom of the schematic. Neil Young's Les Paul Guitar "Old Black" and Tech Larry Cragg. 3, SEL JR-5347-2, BIAS=17, ENG=88, AVG=5000. These tubes are compatible with 5881 and any 6L6. The 6L6 was first introduced by RCA in 1935 and interestingly enough, the first version had a metal envelope and was the first true beam tetrode ever made – ANYWHERE! All the successive versions however, had a glass envelope and over the years we worked through the 6L6G, 6L6GA, 6L6GB, 5881, 5932, 7027, and the final v. Watch Queue Queue. [In German.
