Hi guys! Not sure if this the right place to ask so ....I made an "adaptation" of the Gravitywave PCB for my CNC and assembled a couple of boards. Tested the various voltages without the ICs and i get everything more or less correct on the tl072 and lm324 with 8.70v but on the pt2399 0v!!
So I tested the 78l05 and I saw that nothing is coming out
So I took out a fresh one, tested 9v going in, 5v coming out
Replaced the one on the board with the fresh one and again 0v coming out so I assume something is frying the voltage regulator....
Anyone tried that PCB design?
