VPS1 - Premium Tube Mic Power Supply

The "VPS1" is our custom, premium tube mic power supply, designed and built in the US. Rather than the Zener-regulated design found in most Chinese-made power supplies, we use a MOSFET-regulated design with significantly improved filtering. Features & Benefits Low drop-out regulator ensures voltage regulation despite temperature and AC line variations Adjustable B+ voltage (via internal trimpot) Adjustable heater voltage (via internal trimpot) allows compensation for voltage drop in long or sub-par XLR7 cables Multi-stage noise filtering Large heatsinks ensure lower operating temperature and long-term reliability Soft-start heater voltage (4 second ramp) eliminates power-on current surge, to extend tube life Voltage filtering in pattern selection circuit to eliminate "pops" when changing patterns Neutrik XLR3 and XLR7 connectors US milspec silver/Teflon wiring Durable, powder-coated, vented lid (handmade in California) AudioQuest IEC power cord with long-grain copper and semi-sol
