Hi Im making an LM3876 based amplifier, but needs an inductor. (0.7uH) Iv'e bought some from futurlec (part no IND00068) on 0.68uH, don't know if I can use them? I've read some different guides on LM3876 building, and I can read that I can make one myself with some 0.40mm coated wire wounded 10 rounds around a 10 ohm resistor. I only have 0.20mm wire, can I use that, but eg. with another amouth of rounds? I can only find a "air inductor" calculator, but you can not set other wire diameters in. This is my first amp, so I got a lot of questions.
