Custom DIY Upgraded Home Amplifier

Description

Selling a fully modified and enhanced SPL-1000 amplifier (Custom DIY Upgrade). The original enclosure was reused, but all internal electronics were replaced with high-quality, high-fidelity components. Forget the original factory circuit, which was very weak and failed to deliver its rated power. This project was designed with reliability, safety, and sound quality in mind. Key improvements and features: - Independent high-fidelity amplification modules (one per channel). - Symmetrical 47V supply, delivering an estimated real output power of 2×180W RMS into 4 Ohms (guaranteed real power, without premature distortion). - Speaker protection board with relay (blue circuit): prevents "pop" noise at power-on and protects your speakers from damage in case of failure. - Reinforced power filtering and rectification (a bank of four robust capacitors on the brown board), ensuring tighter and more stable bass response. - Intelligent cooling system: the rear fan features thermal control and automatically increases rotation speed according to the aluminum heatsink temperature. - Extremely clean, well-organized, and oversized internal wiring for enhanced safety. Ideal for users seeking a robust amplifier for background music, small parties, cafés, or studio monitoring — with the assurance of a reliable circuit that safeguards connected equipment. Hand-delivery available in the Murça area, or shipping via courier at buyer's expense.
