This power supply is meant as an auxiliary or as a permanent power supply for all common circuits based on a stabilized DC voltage between 3 and 30V provided that the consumption does not exceed 3A. Of course this power supply unit can also be used for other purposes. Be replacing the trimmer by a potentiometer, it may even be used as an adjustable power supply unit. A good quality heatsink must be used. Circuit diagram: 3 TO 30 Volt 3 Ampere DC Power Supply Circuit Diagram Parts list: R1 = 8.2K R2 = 2.2K R3 = 680R R4 = 1K R5 = 82K R6 = 0.18R/5W C1 = 470p C2 = 100nF-63V C3 = 100nF-63V C4 = 100uF-63V C5 = 10KuF-60V D1-D6 = 6.6A Q1 = MJ3001 (Darligton) IC1 = UA723D Specifications: Overload protected Sshort-circuit stable Output current: max. 3A Output ripple voltage: 0.5mV Output voltage: adjustable from 3 to 30V, stabilized Input voltage: 9 to 30V AC (depending on the desired output voltage)

3 Band Tone Control circuit uses an op-amp as an amplifier end. Tone Control circuit is a regulator of tone bass, midrange and treble or 3 band called because it can set the three tones. Filter circuit is applied to the series of "Tone Control 3 band" This type baxandal like the title of this article.  Results filtering regulator tone or tone control baxandal type is good, because there is no signal level is wasted directly into the ground. Range frequency tones generated from Tone Control 3 band was determined by the configuration of the R and C of the filter section baxandal. As an amplifier on Tone Control The set of three band use traditional IC LF351 has slewrate high and high input impedance. For more details, series 3 Band Tone Control as follows. Figure Series 3 Band Tone Control 3 Band Tone Control circuit above using LF351 Op-Amp is used to strengthen the signal after filtering by the filter process baxandal. Level tone Bass, Midrange and Treble settings are determi...

These amplifiers using IC KA2202 and KA2207, which has a power output of 2.3 Watt berimpedansi 4 ohms. Minimum supply voltage and maximum 5Volt 20Volt. See schematics and component list below.
