Very simple preamplifiers using 2N3904

Hi, Friends. Today I get email from Kunal Banerjee, send a preamplifier projects to published for all to see. It is very simple preamplifier circuit using one 2N3904 transistor only. Though very small, but it still have many useful. He say it low noise than normal IC circuits. and extremely low distortion. Frequency response: 20 […]
