Another wonderful Florida sunshine and another great kit.will test later. THANKS FOR VERY FAST 3WEEK SHIPPING TO USA.VERY NICE LAYOUT.ALL COMPONENTS PRESENT AND ACCOUNTED FOR.FOR THOSE WHO ARE CONCERNED REMEMBER THIS CIRCUIT CONVERTS AC TO DC THE FOUR DIODES CONFIGURATION IS A FULL WAVE BRIDGE RECTIFIER..

This is a great kit for the price but unfortunately the kit came with 3 incorrect parts. Wrong voltage capacitor (too low), wrong polarity output terminals (colours transposed) and incorrect screw size for the heatsink. Also the voltage control works in reverse to normal, turn it clockwise and the output voltage decreases and vice versa, and the on/off switch only disconnects the output voltage but the input supply voltage is still powering the circuit. However in my opinion it's still good value and the incorrect parts issue has been reported and hopefully should be rectified.
