This circuit consists of two identical intercom units. Each unit contains a power supply, microphone preamplifier, audio amplifier and a Push To Talk (PTT) relay circuit. Only 2 wires are required to connect the units together. Due to the low output impedance of the mic preamp, screened cable is not necessary and ordinary 2 core [...]

Please see Schematic on left your hand. light adjustable circuit with IC 4017 IC556 and IC 4017 in Traffik Control of light – in the catalog of amateur radio resources to … The circuit uses IC 4017 [...]
I see in the data sheets that the OPA541 can deliever 5A continuous and +-40V on the supply side. subwoofer circuit The OPA549 can deliever 8A, but can only handle +-30V on the supply side. Here you can opa541bm, simply use a link from the period after the defeat on each chip back 1 / [...]
The work of the power supply is the gain of 2N3053 2N3906 and 2N3904 is fixed internally at 2Watts. 2W switch power supply circuit It is to compensate the reduction of output power due to low voltage supply the transistor uses the Bridge-Tied-Load principle (BTL) which can provide an output of around 1.5 to 2 [...]
LM317 Variable Power Supply Regulator A circuit is timeless. LM317 regulator is a versatile and highly efficient 1.2-37V voltage can provide up to 1.5 Amps. of current with a large heat sink. It is ideal for almost any application. This was my first power source workbench and I still use it. Since LM317 is protected [...]
