1. Size and Weight: 6L6GC tubes are larger and heavier than some other power tubes, which can make them more difficult to transport and install.

2. Power Consumption: These tubes consume more power compared to some other types of power tubes, which can result in higher electricity bills.

3. Break-In Period: Like all tubes, 6L6GC tubes require a break-in period for the best sound quality. This can be time-consuming and may require patience.
