I know my English is somewhat mangled, but I don't know what the real question is ...
I want to start on the Gilmore amp soon, but I can't get 1.6V LED's. The basic LED's here in Oz vary from 1.8V to about 2.1V.
So what are the formulae/calculations/changes to be made to the components? I presume the LED is trying to achieve a bias voltage on the base of the 2SA1015 and the 2SC1815 but what is that voltage (is it 16 - 1.6?), how do I calculate the changes and what components are to be changed?
I know Sijosae has a schematic on Headwize which uses 1.85V LED's but he is also using a 12V supply rail.
Help, please.
