Description
Preamplifier RagnaMos 1.5
This preamplifier is built around a small MOSFET, the BS170. The current source is composed of a JFET 2SK170. The gain is just under 4x. The power supply is filtered by a simulated inductor and then divided into two capacitance multipliers. The input and output decoupling capacitors are of audio-grade quality.
This preamplifier is very dynamic with a slightly warmer tone and a very detailed sound.
