Phase Linear 400 Amplifier 15KuF 100V Capacitor Upgrade Assembly! PL-400 PL 400 Series 2 Hello, we are White Oak Audio Design! Description of Item: FOR A LIMITED TIME, YOU WILL RECEIVE A COMPLETE, PROFESSIONALLY ASSEMBLED CAPACITOR ASSEMBLY (AS SHOWN IN THE FIRST PHOTO BELOW). ALL THAT WILL BE LEFT FOR YOU TO DO IS A SIMPLE WIRE ATTACHMENT AND MECHANICALLY INSTALL IT USING THE NEW HARDWARE PROVIDED. We have transitioned to the round capacitor board style shown in the first picture instead of the rectangular ones shown in the later photos. Over time, we will update all photos.White Oak Audio offers the premier PL400 and PL700 Capacitor Upgrade Kits on the web. These are professional-class upgrade products, meticulously engineered to look and perform better than the original. NOT NOS CAPACITORS. THESE ARE BRAND NEW CAPACITORS CUSTOM MANUFACTURED TO OUR SPECIFICATIONS. Do you own a Phase Linear 400 Series 1 or Series 2 Amplifier (the one with the 2 big VU meters or LED Cylon meters)? It is a great amplifier but it has always been deficient in bulk storage capacitance in the power supply. Coupled with that, 40+ years has taken its toll on the performance quality of the original capacitors installed in your amp. You are not getting the bass punch that this amp is capable of and you are living with a noise floor that is far worse than it can be. Here is your opportunity to replace the original pair of 5900 uF 85V capacitors (some vintage PL400s may have differing values) with a high-quality, long-life 15,000 uF 100V replacement pair. DO NOT REPLACE THE ORIGINAL CAPS WITH 80V CAPACITORS! THE POWER RAILS IN THE PL400 TYPICALLY RUN 80-82VDC. Capacitors made new today do not have the extra margin that the original capacitors Phase Linear used and you could end up with a mess to clean up inside your amp if you use under rated capacitors. For reliability and long life, you should operate electrolytic capacitors at a maximum of 80% of the rated voltage. 80% of these premium 100V caps is 80V leaving you with plenty of margin. DON’T CHANCE YOUR COLLECTIBLE AMP with 80V caps!! This auction is for a brand new, fully assembled, bulk capacitor upgrade to replace the original worn out electrolytic power supply capacitor pair with brand new pair of modern high capacity electrolytics. Like all White Oak Audio Products, this kit is a direct drop in for the original. The results below speak for themselves. This scope trace is what your power supply voltage rails looks like BEFORE the upgrade while playing normal program material at ~2W output: This scope trace is what your power supply voltage rails will look like AFTER the upgrade while playing normal program material at ~2W output (Yes, the scale is identical between the two scope traces): This auction is for the complete, ready to install assembly including all the electronic components as shown in the photo above and the link to the installation instructions and documentation. The components you receive in your assembly may differ slightly in appearance from those above due to parts changes by the component manufacturers. Quick and easy installation involves: Removing the top cover from your Phase Linear amplifier Removing the faceplate assembly from your Phase Linear amplifier Removing the original capacitor hold down bracket. Removing your original bulk capacitors Removing the wires from the original capacitor screw terminals Reattaching the wires to the new White Oak Audio capacitor screw terminals Re-installing your new White Oak Audio bulk capacitors Reinstalling the new White Oak Audio hold down bracket Carefully dressing and neatening up the wiring and assuring wire clearances Reinstalling the faceplate assembly on your amplifier Reinstalling the top cover on your Phase Linear amplifier Enjoying your new upgrade Your bid is for exactly what you see in the picture above. Detailed photographs, assembly parts list and “crystal clear” installation instructions are located at this link below: Phase Linear 400 Cap Upgrade Assembly and Installation Instructions New capacitor specifications: Total capacitance per rail: 15,000 +/-20% uF vs. 5900 uF original (some vintage PL400s may have differing values) DC working voltage per capacitor: 100V steady state/125V surge vs. 85V steady state/100V surge original Capacitor maximum operating temperature: 105 degrees C vs/ 85 degrees C original Capacitor maximum ripple current: 8A maximum at 120 Hz, 105 degrees C for each capacitor Capacitor maximum ESR: 0.021 ohms maximum at 120 Hz, 25 degrees C for each capacitor This upgrade assembly is easy to install but requires some skill. While installation is not a difficult procedure, the installer should be familiar and comfortable with working on electronic equipment and using associated tools and observing proper safety practices. If you are not familiar with working on electronic equipment or do not possess the proper equipment, it is recommended that you take your amplifier to a service technician that can perform the Capacitor Upgrade installation for you. Complete and ready to build kits are available from White Oak Audio Design (Bing it to find web address) or possibly on Ebay if we happen to be running such auction at the time. Watch for other innovative Phase Linear upgrades that are always coming from White Oak Audio Design.Photos of the finished project are shown below (installed in chassis before and after). BEFORE: AFTER: Applicability of Kit: The White Oak Audio Design PL400 Capacitor Upgrade Kit replaces only original Phase Linear 400s that are equipped with 1.75 diameter by 4.125 long screw terminal capacitors as shown in the above figures. It is not for replacement of any other type capacitors or terminal configuration. If your original Phase Linear amplifier does not match these requirements, do not install this kit without contacting White Oak Audio Design first for guidance. This kit is being sold as NEW with no returns (due to potential damage to the circuit assemblies once assembly has begun).
