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.
