Here is the 250W RMS power amplifier circuit called Legend-Stage Master. This is the previous version of Legend-Stage Master MK2. The circuit is based on power MOSFET and give a great output performance for indoor audio sound system.
This is 500W RMS power amplifier circuit design, build based on MOSFET. The circuit is very popular in EE audio hobbyist as “LEGEND stage Master MK2”. It is a very good and powerful amplifier. It uses 12x power MOSFET IRFP240.
This is the circuit diagram of 2 x 22W stereo car audio amplifier. The circuit is powered by a single IC TDA1553 with some external components, this IC will handle your stereo car audio system. The TDA1553CQ is a monolithic integrated class-B output amplifier in a 13-lead plastic DIL-bent-SIL power package. It contains 2×22 W… Read More »
Here is the 100W RMS audio amplifier schematic diagram: This circuit is quite simple but will give you high quality audio output. Take a note that above diagram designed for single input and single output (mono system). For stereo system, you need to build two similar circuits.
There are many version of stepper motor type, also the many version of stepper motor controller design. This circuit is a general-purpose stepper motor controller that use IC TDA2030 as the driver. This circuit can be used with a wide range of operating voltages, from approximately 5 V to 18 V. It can drive the… Read More »
This the Good Quality FM transmitter for your stereo or any other amplifier gives you a pretty good signal strength up to a range of 500 metres having a power output of about 200 mW. This circuit can be operated with a 9V battery. The audio-frequency modulation stage is constructed close to transistor BF494 (T1),… Read More »
This is the circuit diagram of DOD FX75 Flanger guitar effect pedal. The circuit drawn by Fabian P. Hartery. Featuring a Width control and two output jacks, the FX75 was much more versatile than its predecessor, but the flanging effect it could provide was still not very intense. That said, chorus-like washes of flange can… Read More »
