- | Aging components should be replaced. | + | If your main power capacitors are from the IC brand, generally shipped in light grey as shown below, they are low quality chinese capacitors which are prone to leak, seriously reducing amp performance. |

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. | Resistors R78 and R79 of the low voltage part are 5W 470 Ohms, but are exposed to transients up to 4.9W (48V@470Ohms).
