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 [...]
Home security project Securiy is a matter of great concern to all of us in this world. Normally there are four types of security threat to our property.
This circuit is an oxygen sensor for car. The oxygen sensor simulator as built on a protoboard. Note the cigarette lighter plug used for power source. The adjustment knob is at the left, and the switch is on the right. The red indicator LED is in the middle. Only use red, because the voltage drop [...]
The Monitor Test program is a Windows application which comes in the help of electronics technicians for adjusting computer monitors and for general users for testing the quality of their monitors.
