Small stereo amplifier,low power, less devices, IC TDA7025 is the main equipment. Operation of the circuit, the signal split into left and right through the capacitor coupling of C1, C2 is a variable resistor VR1 adjusts the strength of the Continue reading
This circuit is OCL audio power amplifier 100 watt RMS. It use voltage power supply +40V/-40V at 3A current. Main part are power transister no. 2SA1215 and 2SC2921. and have op-amp iC input for preamplifier. Circuit100W OCL Amplifier circuit by Continue reading
This is Circuit Power Amp OTL circuit power amp OTL 100W by transistor 2N3055 (with PCB) circuit Power Supply 98V 5A FOR power amp OTL 100W by transistor 2N3055 (with PCB) PCB power amp OTL 100W by transistor 2N3055 (with Continue reading
Circuit Power Amp OTL 50w With LM3900, 2N3055 This be power amp OTL 50Watt use IC LM3900 and 2N3055 x 3pcs transistors to pillar equipment. Follow very circuit keeps to are Class ab then have a voice good loud. When Continue reading
TDA2009 Ampl BCL (bridge amplifier) 18W ,Supply volt = 23V 2A The TDA2009 be 10 +10W STEREO AMPLIFIER integrated circuits interesting again the one number. We try to bring do the circuit amplifies 18W sizes better or Power Amplifier BCL Continue reading
This is mini Power Amplifier OTL for Cassette Radio Booster. it have transistor TIP41 + circuits of TIP42 Drive speaker sound. Volt supply see in image.
When you want to enlarge sound signal from all source before costume amplify. Usual use Pre Amplifier or Pre Amp. Today I begs for to suggest again the one circuit. That interesting because of use Transistor just one ( the Continue reading
The TDA2030 be the integrated circuit amplifies that highly popular the one number. From this circuit be power amplifier OTL. The electric power about 15W when use 8ohm loudspeakers. But must use power supply the size is appropriate with in Continue reading
This is Power Amplifier Genneral Purpose circuit,main part is IC TDA2030. It is OTL Amp 10W rms at 8ohm.
Today we come to see Bridge Amplifier very small-sized about 6Watt only. This work uses the integrated circuit number LM380 then build easy and economize good. When a friend uses 8ohm loudspeakers. Will have the electric power about 6Watt that Continue reading
