Hello! I am trying to replace an analog meter with a newer LED version in an amplifier, but am having problems with the input. What I want to do is display a max physical voltage of 0.28V (the max needle deflection of my analog meter) when I have my 30 LED's lit. I tried to find some sort of doubler/quadrupler circuit on the web to increase my voltage, but can't seem to figure out how to satisfy the input for the chip(s). Can this even be done? I was hoping not to modify any existing circuits in the amp. Any help will be appreciated.
