Tube 807 Push Pull Amplifier Stalien Stalien 807 integrated amplifier uses 807 tubes in triode mode, chosen. The amplifier has enough control and power. They went on to say of the new amplifier: “Sound is quick, dynamic, opened and draws you into listening to music. Look for schematics with 6L6GC tubes, it's essentially the same tube. Menno even published a SE 807 amp, the 'Maurits', if I recall correctly. I used a 807 PP in triode amp for years, very nice sound and cheap to build. Get your transformers from Wil Blaauw www.ae-europe.nl. Be sure to NOT order the transformer set for the Annastacia:-).
This is the circuit diagram of 35W Tube Power Amplifier with EL34. This tube amplifier designed in 1953 and worked from 1954 until 1989. If you’re interested with classic circuit and classic components, then you should try this circuit. The circuit is interesting but i think it is hard to find the tubes.

It is a classic design of power amplifier 35 W using tube, with two EL34 in connection Push-Pull, by Siemens & Halske, with design date 03/24/1953 and code SV410 / 1. Download microsoft excel for mac free. The amplifier worked from 1954 to 1989, whenever and went off, with an average lifespan of 15 hours a day. Showed no particular damage beyond the replacement tubes, resistors and capacitors, resulting from natural wear.

A significant change was the replacement of the rectifier device of lamp diodes. The only problem will be for those who try their construction, will be the output transformer (applies to all tube manufactures), because the code is not helpful. Can be replaced with a conventional output transformer suitable for EL34. During the construction, it is need (applies to all circuits respectively) enough electronic experience and attention to the high voltage, electric shock risk.

Version 10.0: 'Cheetah' On March 24, 2001, Apple released (internally codenamed ).The initial version was slow, incomplete, and had very few applications available at the time of its launch, mostly from independent developers.
