I have for sale a Phase Linear 4000 Autocorrelation Preamplifier. Shows some nicks and scratches but overall it’s in good cosmetic condition. Please inspect photos carefully as they form part of the description. Estate sale find so I don’t know too much about the unit. Plugged it in and heard a click but no lights and no sound. There was a very loud pop when the “PK Unlimit DN Expand” switch was flipped but it seemed to have subsided. It may come back though. No further testing had been done. Missing all the knobs but the levers tips all seem to be present. Also missing one rubber feet on the bottom. The potentiometer's shafts are also very stiff to turn. Given the issues and very limited testing, this unit is sold STRICTLY AS-IS for parts or restoration. Please message me if you have any questions.**USA buyers, please read: Please note that I cannot generate a USA return label from Canada Post. Therefore if we agree on a return, you will need to get a shipping estimate from USPS and send me a screenshot of the details and amount. I will reimburse you via PayPal. If you disagree with this, please do not make the purchase of this item. Thank you for your understanding.
