Retro Instruments 500 Pre

The Retro Instruments 500Pre design purposely has the limiter effect of tube amplifiers. The Retro 500-PRE works within API 500 rack power limitations. The Retro 500 PRE uses three 12AT7 tubes that are readily available as new production or new-old-stock. A user can select from a wide variety. Your unit uses the new production TAD 12AT7 and these tubes are expected to last for a very long time under the 500PRE operating conditions. We use soft-start circuitry that minimizes stress to the tubes and power supply. The 500PRE takes less than a minute to warm up and perform.

Each 500 PRE consumes 160 ma of power, slightly above the 130 ma VPR-compliant allocation. We recommend racks with quiet linear power supplies like the API models. When power requirements are observed, the rack and 500PRE will provide years of reliable service.
