This is simply stereo audio high impedance preamplifier with two 6J1 tubes in wiring as a triode. Board needs 12V AC power supply and maximal voltage at board is around 60V DC. This is a small safe voltage for your experiments. It is a preamplifier with high impedance input and output. Ideal for amplifying the signal from a microphone, for audio sound cards or high-impedance headphones.
⚠ ATTENTION! Does not work with classic speakers and low impedance headphones at the output. A transformer must be used for low impedance output.
