Product Details:

 

Based on the classic Musical Fidelity A1 amplifier circuit. ​ ​In pure Class A working condition, due to the high heat generation during operation, a symmetrical left and right heat dissipation structure is used, and the tooth shaped heat dissipation is efficient. (10mm heat dissipation substrate, CNC precision machining) ​ ​Symmetric circuit design, dual channel power amplifier board output. ​ ​Use A-core high-power Toroidal transformer. ​ ​Use large capacity main filtering array. (Each channel uses 4pcs of 8100uF/63V Siemens capacitors, with a total filtering capacity of up to 64800uF) ​ ​Use 1 pair of ON MJL21193/MJL21194 per channel ​ ​Use Omron relays. Prevent switch on/off shock and DC output protection, aluminum alloy contacts, good stability, to safeguard your equipment.
