Bypass LED blinks due to PS adapter blinking..
"Something" severely loads PS with first suspect being LFO..

Definitely not.  If your PSU is periodicaly cutting out (i.e. trying to protect itself), then something is wrong as Antonis suggests.  You need to find the source of the problem (likely a short) rather than try to throw more power at it!

Show us what you've built.

And a belated "welcome", btw.  :)

There's your short-circuit.

Did you build a mirror-image version??  ???

Everything that should be on the "left" appears to be on the "right", and vice versa.  The layout shows the view as it would be from above the board.

Deep breath.  Take a drink.  Initiation completed!   :icon_cool:

Come back and share the results when you do the second iteration, and we'll take that drink with you.  :)

also welcome, and I was going to say, because you've used sockets ....... but I see that's only partly true. if you can remove all three IC's, just carefully solder them to the underside of the board, and the pin numberings will magikally correct themselves.

or something. and then probably rebuild it.

If your PSU is still wigging out, then it's still likely protecting itself from a short.  (If you use a battery, does it get warm?)

Get out that magnifying glass!  And use your DMM to confirm there is indeed a short (or not).
