Readings are: Top of cathode = 5v EL84 (1) cathode =5v EL84 (2) cathode = 5v would this be (1)5v + (2)5V = 10v total El84 Push Pull Amplifier Schematic If I wanted to build a parallel push-pull output stage using four 6BQ5/EL84 tubes output transformer as used on the Dynaco (tm) ST70 and MkIV amplifiers. I was looking for a simple and cheap circuit to build, and I chose this one because I already had most of the parts. Hi fi world may by gerry radford issuu. the cathode-biased single-ended output stage is somewhat simpler to understand than that of the push-pull amplifier, as a SE stage is similar to a typical pentode stage used in preamplifiers. Эта статья продолжает наш разговор об однотактных усилителях мощности.

Where I don't want to slog through in a half-understood language, I use Google's translation page. 00 to $168. ANK Audiokits L3 EL84 Triple C-Core Integrated or Power Amplifier. My question is: Do I add up both cathode readings from each tube. new registrations are closed at this time easy 6v6 schematic. C $353. This requires almost 30 volts of swing on the grids to drive the amp to saturation. Schematic of the amplifier See our non-profit green energy site here: http://www. I haven't done too much in the way of optimization, or tweaking, but it sounds pretty good as is.
