IC - PT2305 Supply Voltage- 5V Operating current - 30mA all the ground pins must be connected to oV (-)

BE CAREFUL ! You are going to handle 230v  make the circuit and test  carefully! The LDR face needs to come off of the cover of the bulb, as the bulb works depending the background light condition.And also you must be clever to fix LDR on a place that will not fall LED light of its own 230 v -[Neutral , Phase ]

this is a mono circuit.you can input audio signal to input and the output to the amplifier. S1 and S2 can be used to up and down volume

Need 28-35 v full wave transformer Use 8 inches woofer or sub woofer(sub woofer is better electrostatics must be more than 100v rated Q4 to Q7 must have heet sink  use a pcb for better quality 28v ෆුල් වෙව් ට්‍රන්ස්ෆොමරයක් නම් වඩා හොදයි අගල් අට සබ් වුෆර් එකක් හො වුෆර් එකක් ඉලෙක්ට්‍රොලයිටික්ස් සෙරම 100 වොල්ට් වලට වඩා එවා ඔනෙ Q4 ඉදන් Q7 ට්‍රන්ස්සිස්ටර් වලට හීට් සින්ක් ඔනෙ වෙනවා

Need a preamp ? with Bass Treble Volume Balance Loudness Here it is Make sure Supply Voltage is 12V *note :- all the ground pins must be connected together to minus v pin

Here is a LED display circuit for preamps,amps . this works with 12v .this is the easiest way to make a audio vu meter with best performance .try this  lm3915 pinout

have you ever heard a sound of a laser beam even in a cartoon.then try this 555 pinout

4017 pin out 555 pinout

Maximum voltage- 12v Typical v :- 9v For questions comment down below

 Here is the echo circuit 100% working and tested. All the AGND must be connected to pin 3(see diagram).And also all the DGND must me connected to Ground pin (-) Pins Of PT2399
