Hi Guys I am seeking advice to avoid having to sell at a loss and buy new replacement chokes for a potential amplifier project. I have 2 pair of LL1673 for use in an amplifier power supply that will operate at 135 to 140mA per channel. I had planned to use the 10H-200mA (saturation at 295mA) as first stages of power supply filtering for both channels (270 to 280mA) and the 20H-100mA (saturation 145mA) chokes as the final filter stage for each channel. Is this running them "too hot" and therefore should I look to use the 10H-200mA as final stage filter and maybe risk the 20H-100mA, wired as 5H-200mA in the first stages, or do I need to go to 10H, wired as 2.5H in the first stages and 20H, wired as 5H in the final stage? Cheers Grantn
