Can you provide schematic shwing correct component orientation
Reading through and comparing the all the circuits for the scr phase controller I have noticed there have been a few changes made regarding the orientation of components mainly 12v zener and IN4148 and the removal and install of new components such as capacitors as shown in one of the photos where you are testing with an oscilloscope.
As I would like to build this controller to control the speed of a 230V 50Hz ac universal motor I would be grateful if would you please provide me with a schematic that has all the final changes you made when you tested?
Further to this do you possibly have circuit for a 4 LED voltmeter using a LM324 that can show AC voltage steps, 230, 190, 150 and 110V so as I adjust the speed I can monitor leds instead of looking at my multimeter?
Your assistance would be appreciated
