Once you use one, you will not want to ever use any other soldering iron! By the way, I concur with your evaluation of the Hakko FX888D.

This helps so much. The youtube "how tos" on this help some but this diagram makes it real clear. Thanks! Finally got a schematic diagram that is easy to understand. This helps so much.

Regards Hi,

Would mine be alright if I wired them as such: PSU -> MOSEFT1 -> jam two wires into the MOSTFET1 power input to connect MOSFET2 -> jam two wires into the MOSEFT2 power input to connect the main board? If I remember correctly this should still be a parallel circuit. Would the wires still be able to handle the current?

Word of warning, mine came with no heatsink compound between the mosfet and heatsink. I also found that the heatsink on the inside rear side of the power supply also is lacking the heatsink compound. This compound aids in heat transfer and without it the components like mosfets and diodes can overheat. BTW my A8 is from Feb 2018. To add compound you have to remove the three screws on the rear side (one is under the label). I know this will void the warranty but better safe than sorry.
