Nope.  They look fine.

but i got no delay.. im pretty sure theres no solder bridge/cold joint/short etc.

im running this project with 9v battery and without dc/ac.
do i need dc jack to power up pt2399 chip??
hard to find dc jack that suitable for guitar pedal from my local store and this is why i dont use it

You don't need an external power supply: a 9V battery is fine (although it won't last very long).  The next thing to try is an audio probe: is there any signal going into the PT (pin 15) and is there anything coming out (pin 12).
