When experimenting with tube amplifiers, you ability be abashed about the altered modes of operation, like triode or pentode mode. To accord a little advice i developed this PCB. You can body baby Amplifiers based on 6P14/6BQ5/EL84 easily, and the achievement Power of 2..6 Watts is added than abundant for home use. With this PCB [...]

10 W Bass-boost Audio Amplifier Schematic Description: This architecture is based on the 18 Watt Audio Amplifier, and was developed mainly to amuse the requests of correspondents clumsy to locate the TLE2141C chip. It uses the boundless NE5532 Dual IC but, obviously, its ability achievement will be comprised in the 9.5 – 11.5W range, as [...]

The power amp board has remained unchanged since it was first published in 2002. It certainly isn’t broken, so there’s no reason to fix it. The photo below shows a fully assembled board (available as shown as M27). Using TIP35/36C transistors, the output stage is deliberately massive overkill. This ensures reliability under the most arduous [...]
100watt Amplifier bipolar circuit This is a basic 100 watt power amplifier designed to be (relatively) easy to build at a reasonable price. It has a better performance (read: musical quality) than the standard STK module amps that are used in almost every mass market stereo receiver manufactured today. When I originally built this thing, [...]
