Yesterday i went out for a small test of my MFD (not for detecting..).
I changed the preamplifier with another different with gain x30. Also i replaced the first Op.Am. Now there is not horizon problem. Why???? I can't understand ![]() ![]() Also, can Esteban tell me if the x30 gain of the pre amplifier is enough??? Regards

Hi Esteban.
Resistors 1% are better for lower noise, but i think that at my MFD i use 1%. The 90% from the resistors that i have are 1% tolerance. And something else... i see that when the first or second led is bright, it is not full bright but it flash ![]() Regards ![]()
