Re: 80W efr tube. How hard can I drive it?
There are different models of 80w EFR tubes. For mine, you never want to exceed 28 mA and EFR states that 25 mA is the maximum if you want to get the maximum life out of your tube. Go to the Lasea EFR website for complete specs for your tube. You cannot rely on percentages from others because 1) you may not have the same model of EFR tube and 2) it is highly likely you will not have have the same brand and model number of power supply. Different power supplies result in different output for the same programmed % number in your Ruida controller.
Keep the cooling water around 18C for best power consistency and long life.
