number of amplification stages and tube power is hidden inside.<\/p>\n<p>In this amplifier circuit without common feedback, two low-power 12AX7 triodes (first and second amplification stages) and a pair of 12AT7 dual triodes (third and fourth stages) operate.\u00a0The passive RIAA corrector is assembled on polystyrene and polypropylene capacitors.<\/p>\n<figure><img loading=\"lazy\"
