Jeff Rowland - (2) PC-1's :Power Factor Correction Conditioners with CARDAS Power Cords

I have (2) Jeff Rowland PC-1 's for sale - I prefer to sell as a PAIR for $1400 or $750 each. I also have aftermarket CARDAS Power cords for these that are included in the price.

Certain JRDG components, equipped with universal voltage auto-sensing and auto-ranging switching power supplies, can be connected directly to a PC-1 without any modifications.

Namely:

• Model 102 stereo amplifier.
• Capri preamplifier.

Certain other components, equipped with single voltage switching power supplies. Can be connected to the PC-1 only after converting them to 240V operations.

Namely:

• Model 201 monoblock power amplifier.
• Model 501 monoblock amplifier.
• Continuum 250 integrated amplifier.

The Jeff Rowland Design PC-1 is an advanced external power rectifier and conditioner based on the same Active Power Factor Correction [PFC) technology incorporated in JRDG reference amplifiers such as the Model 625 stereo power amplifier and the Continuum 500 integrated amplifier. PC-1 has been designed to bring the exceptional sonic and musical benefits of power factor correction to those JRDG amplifiers that feature switch mode power supplies, but do not incorporate internal PFC-based power rectification circuits.

Through a multi-step process, the PC-1 provides a noise free DC power stream at up to 385V, isolated from the grunge of the typical AC mains grid. The high voltage clean DC maximizes the performance of all highly regulated switch mode power supplies incorporated in compatible JRDG power amplifiers. The PC-1 synchronizes the current and voltage sinusoids from the AC mains, and then uses the resulting highly optimized AC to generate an invariant DC current and voltage. A final step cleanses the DC power from any residual voltage or current fluctuations, ripples, or unwanted noise through a large bank of charge capacitors. A PC-1 features a single output power connector, 2 components may be connected to a single PC-1 through an optional Y pigtail.

Please note that the PC-1 can be connected only to components that incorporate switch mode power supplies. Furthermore, any compatible component must have been pre configured to operate at 220VAC prior to connecting it to a PC-1, or the compatible component must be equipped with an auto-sensing and auto-ranging switch mode power supply. Connection of a PC-1 to an incompatible component, or to a compatible component configured for 120VAC operation, will result in significant damage to the component or to the PC-1.
