PSU HY5003 more amps mod

Post by exxos » Mon Nov 13, 2017 11:17 pm

Brought from.. ... 3a-85-1938

3amps output.. after adding a larger cap and resistor.. 5amps output :) Heatsink gets a lot hotter so only good for short uses..

Not much more info here, as was done a few years ago... Looks like I added 1K? across R15.
