SLV BL12 Capacitor Bank Board – Professional Power Filter PCB

The SLV BL12 Power Filter Board is the heart of the amplifier's DC power supply. Designed to support the high-current demands of Class H architecture, this board features a massive array of ten high-capacitance electrolytic capacitors. This "reservoir" ensures that the BL12 has the instantaneous energy needed for deep subwoofer "punches" without voltage sag, maintaining sonic clarity at extreme volume levels.

Key Features & Build Quality

• 10-Capacitor Array: Features space for ten high-voltage, high-uF electrolytic capacitors (typically $10,000\mu\text{F}$ to $15,000\mu\text{F}$ per unit in the BL12).

• Dual Bridge Rectifier Support: Engineered to mount heavy-duty metal-cased bridge rectifiers with dedicated heatsinking for converting AC to stable DC.

• Reinforced Copper Traces: The PCB utilizes extra-thick copper layers and wide bus-bar traces to handle the hundreds of amperes flowing to the Class H power modules.

• Onboard Rail Discharge: Includes high-wattage bleeder resistors to safely discharge the capacitors when the unit is powered down.

• Voltage Rail Distribution: Designed to manage the multi-step voltage rails characteristic of Class H systems, ensuring clean power distribution to both the low and high-voltage stages.

Technical Specifications (BL12 Profile)

• Compatibility: SLV Black Series BL12.

• Configuration: 10-Slot Capacitor Bank.

• Circuit Type: High-Current Dual-Rail Power Filter.

• Input: High-current AC from the toroidal transformer.

• Output: Stable DC voltage rails for the BL12 Class H modules.

Applications

• Power Supply Repair: The primary replacement for amplifiers experiencing "hum" or signal ripple caused by aging or dried-out capacitors.

• Performance Restoration: Essential for fixing units that "clip" prematurely due to an exhausted power reservoir.

• Custom Amp Engineering: A heavy-duty power filtering solution for custom-built professional audio equipment.

DANGER — HIGH VOLTAGE: This board stores a massive amount of electrical energy even after the amplifier is unplugged. NEVER touch the capacitor terminals or the underside of the PCB without verifying that the voltage has fully discharged (0V) using a multimeter. Failure to do so can result in a lethal electric shock or severe burns.
