MAC Rack kit Build Thread from October 2016 with slow attack led

and the SC Top & Bottom.

[Joe Malone]

Hey Joe,
Found the issue on the SC board (I think) after re-checking every component-I had the 79L12 and 78L12 line voltage regulators switched.
(I am supposed to have the C18 .1U cap installed- correct?)
Pretty sure I fried them in the process of getting them out so are these fine replacements?
(from Mouser)
LM79L12ACZ/LFT4
LM78L12ACZ/LFT3

Thanks!
Jake.

OK that will do it. Replace the 78L12 & 79L12 regs as they are most likely dead and replace 1 or both of the zeners if they test short circuit.

Yes those mouser parts look correct and any 24v 1Watt zener will work in there as well

The dINgO-T build looks fine. Just solder link the GND and CHS solder pads together under the pcb or above next to the L bracket.

Get both dINgO-T connected to power and check power doesn't hiccup. Then reconnect the good sc and check power up and then the repaired one until your power doesn't hiccup and then you will be ready to calabrate.
