The design comes from the 10th anniversary of the Forum TDA1541 line.

Several bugs in the original circuit diagram have been modified (should be the pit left by the designer intentionally);

PCB board uses FR-4 military grade, 4 layers of circuit, 2.0mm thick, sunken gold design.

Selected fever-grade components: AB non-inductive carbon resistance is used in the digital part, 15PPM in Taiwan is used in the power supply and analog part, and the error is 0.1% metal film resistance (one thousandth of the error, the error color ring is purple, and one percent of the error in brown); WIMA Weima brand is used in the film capacitor, Siemens and ERO are used in the part; Nikon 6 is used in the main electrolysis. 3V3300uF, Lotus Root Removal is Panasonic 120uF, IC seats are all authentic Taiwan Linggong gold-plated round hole seats, 6 use only the original imported genuine JRC5534DD. Detailed pictures can be viewed by oneself, physical shipments are consistent with the pictures.

The board has been debugged and plugged in TDA1541 to listen to music for more than 2 hours. When the buyer receives the board, he only needs to connect the power supply and plug in SAA7220 and TDA1541 to use it normally.

Plate size: 200*160 (excluding terminal protrusion size)

Power requirements: dual AC15V + single AC9V
