12Vdc to 9,7.5,6 Vdc circuit This simple converter using a Zener diode and a transistor into a 9V DC 12V DC battery power to the maximum 1A. The circuit is very simple to build, and requires only 3 electronic components, resistors, zener diodes and transistors. The 2N3055 transistors, 1N4738A Zener diode or Zener voltage and the [...]
The EL84 is one of the best pipes ever made, IMO, 3-triode EL84 wired in parallel and replace a sonically outperform WE300B in the same circuit (circuit originally 300B). 5W Tube Power Amplifier with EL84 And each of you probably know, I’m not a fan of tubes parallel to all.I would be very interested to [...]
car converter 12 to 9 Vdc circuit This car converter 12 VDC to 9 VDC converters side for audio ,playstation,DVD,tv etc., is that we have designed for 12DC to 9DC converters that we bring to our design circuit . They are all effective in Switch Mode Power Supplies regulated output. We have developed a series [...]
