Yes,
Rita from Meiju is nice, and confirmed original LM561C

just avoid Bava, got boards from them with all mixed diodes...
zener visibility is varying from diode to diode ... enough for me to confirm they are not ok...

You wouldn't happen to have a couple of their 288's would you? I want to test them before I order 100 of them.

Rita is awesome! She answered all my questions and was on top of everything. I received my boards 3 or 4 business days after she told me she would arrange shipping.

Hey guys...

I found this last day on Alibaba...
They pricy, but looks awesome on a picture 35$x board no heatsink but I think 45$with the heatsink is not that much if they are good like looks on a pic... ordered 2 of them, I'm curious... 8y gold supplier... will see

This is the first Forum I have ever been involved in so I don't know how all this works. But that wiring diagram looks pretty easy to follow. I just don't know if the LED chips that are on the board other than the Samsungs are worth it all I know is everybody wants Samsung boards now.
