- | Install stronger components for LV power stage. | + | Resistors R78 and R79 of the low voltage part are 5W 470 Ohms, but are exposed to transients up to 4.9W (48V@470Ohms). Upgrading these to higher quality 10W wired resistors is encouraged. Notably, installing the resistors slightly above PCB to increase air flow is recommended. |
