Hi,

This post of mine has been closed: https://forum.allaboutcircuits.com/...his-schematic-discussion.160681/#post-1403653

Even though I don't understand how you infer the power supply is transformerless. Perhaps I should have include it in the schematic, but in real life the line is being isolated for sure. For future posts, should I include the transformers in the schematic so you don't close my posts? I have seen many posts here with transformeless power supplies and they remain, so that's why I didn't specify it in my post.

Thank you anyways.

 

The transformerless power supplies restriction seems to be a gray area. Many switching supplies don't offer any isolation from line power, but discussing some mods on PC supplies seem okay. Before I contribute to any such threads, I usually ask moderation if it's an allowed post.

 

Could it be your reference to your other closed thread? If you were going to do it once it's pretty like to be done again.

 

hi Blue,
I would advise, when you post a diagram you include circuit power source details, this will make it clear regarding 'transformerless' or not.
It will also help the members reading your posts in giving the best advice.
