Would it still work if I replaced the step-down transformer with capacitive drop configuration? I sometimes get to repair small house appliances with powersupply problems. I'm thinking of designing small powersupplies to keep at hand so I can immediately replace that part instead of hunting down for the culprit. These powersupplies usually come in capacitive-drop form from the factory. Some of them come with zener diodes at the output in place of the regulators that you're using. I wonder what are the pros and cons for regulators and zeners? One other question is how to calculate and adjust the output power (watts) of these types of applications. Thank you!

[@TEKNOISTIX]

I don't recommend dropping capacitor for variable supply as it is low current and not stable at all

hello sir
I Micky, i am following your for a long period. Sir, i want to make this supply along with SMPS board in a AC stabilizer box ( I have a burnt stabilizer). I have 10 amp. 12-0-12 transformer but it is big to install in the box. can i give input supply of +12 and -12 from smps instead.

Connect 1 and 2 pins of potentiometer together and then connect it with adjust pin
3rd leg should be grounded
For more detail watch the latest video that is uploaded today on channel it is also based on variable power supply

But I connect input negative to center pin to potential meter and adjust pin to 1st pin of potential meter and 3rd pin pof potential meter remain untouched and its working. Is there any problem if I don't common 1and second pin of potential meter
