power-amplifier 2
A friend is interested in building a hi-fi power amplifier, specifically a Class AB model due to its quality sound, particularly in bass response and distinct clarity. This circuit is designed as a hi-fi OCL (Output Capacitor-Less) power amplifier with...
40 Watt Hi-Fi amplifier (TDA1514AN-7)
This high-quality audio amplifier is based on the TDA1514A, a 9-pin flat package integrated circuit. The heatsink must be insulated from the ground. The amplifier can deliver 40 watts into an 8-ohm load with a 27.5-volt power rail or 40...
1W stereo Headphone Amp (TDA2822)
A stereo power amp designed for use in portable players and radios. A 3V supply can be used to drive headphones providing 20mW in 32 Ohms per channel. A 9V supply will provide 1W in 8 Ohm per channel for...
low power 12000 volt power
For generating approximately 12,000 volts DC for an ion generator, this circuit design may be suitable. It draws power from a 120 VAC power line and utilizes a small 6 kV camera flash trigger coil. The output signal is isolated...
25W HiFi Audio Amplifier with MOSFET
This circuit can be directly connected to CD players, tuners, and tape recorders. It requires the addition of a 10K logarithmic potentiometer (dual gang for stereo) and a switch to accommodate various sources. Proper grounding is crucial to eliminate hum...
Audio / Video Distribution Amplifier
With the amount of equipment in home entertainment centers today the need to be able to vary the gain of the audio or video signal is needed. I found this particular circuit helpful when used in conjunction with the Universal...
7W Audio Power Amplifier LF356
The circuit depicted is a low-frequency output 7W power amplifier. It employs a FET input operational amplifier, the LF356, for voltage amplification. The design features a transistor amplifier circuit that includes a driver stage. A significant negative feedback loop is...
High voltage astable multivibrator problem
An oscillator is being developed to operate within the 200V range, targeting a frequency of approximately 1 kHz while minimizing current consumption. Initial testing has commenced.
The design of a high-voltage oscillator capable of operating at 200V and generating a frequency...
Stereo Channels Controller
The circuit includes better channel separation, resulting in an increased stereo effect, as well as reduced noise and hum. This schematic will allow you to cancel or blend left and right channels of your stereo. Uses the LM4136 but at...
