Material Introduction

1. The transformers are all custom-made versions of the Ring Bull. The 1875 version has two 100W, the 7293 and 3886 single-chip versions have two 160W transformers, the parallel version has two 250W transformers, and the Q1 tube version has one 320W and two independent dual voltage windings

2. The volume control is an ALPS 168 four link potentiometer, which can be replaced with an ALPS27 potentiometer for a price difference of 75 yuan (longer service life and higher accuracy). The LM3886 and TDA7293 parallel versions directly use the ALPS27 four link potentiometer

3. The audio input terminal is CMC from the United States

4. The speaker terminal is a pure copper crystal terminal post

Output power: LM1875 rated at 80Wx2, LM3886.TDA7293 and Q1 rated at 120Wx2, impedance 6-8 Ω. SK18752TF parallel version 150W * 2, LM3886 and TDA7293 parallel version rated power 200WX2, impedance 4-8 Ω.
