Phase Linear 4000 Series One Preamplifier Professional Restoration Service

Up for auction is a professional restoration service for your existing Phase Linear 4000 preamplifier...........not the unit itself. You pay for the service and I send my shipping information to you. The return shipping is free once the unit is done. Some things that can't be fixed due to lack of available parts are: broken rotary controls, toggle switches, missing knobs and operational amplifier ICs. I've had very good success on these units if they haven't been serviced before. I rep...lace all the electrolytic capacitors and resolder basically 100% of the molex connectors and the main board connection points. All the controls are treated with De-Oxit and the exteriors is cleaned up. Take a moment to look at the bottom of the unit and count the screws installed. If there are (12) then we are good to go.................anything less than that indicates a very early production model and I don't do restoration work on those. Please check my feedback and bid with confidence.

This auction is valid only within the continental U.S. (due to new insurance restrictions)
Serial numbered units above #2000 should have the 12 screws on the bottom (but verify before purchasing service)
