Title page Capacitor and Audio Upgrade The PRO 80 (also PRO70) is a popular receiver that now suffers from aging electrolytic capacitors. These receivers were made in the early days of surface mount ( SM) components and consequently many now suffer from loss of audio, loss of signal strength or both. Kiwa offers a complete capacitor restoration which includes an audio upgrade. This results in improved audio definition and clarity. Full instructions are included but please note that removal and installation of SM capacitors is difficult without the proper experience and tools (including good eyes!). The capacitor restoration replaces all the electrolytic capacitors. The absolute minimum in tools required should be a very fine tipped soldering iron (temperature controlled a larger 40 to 60 watt iron (flat blade tipped needlenose pliers and a magnifying glass. Capacitor Upgrade Kit .00 Shipping and Handling .00 If you wish Kiwa to install the Capacitor Upgrade the cost which includes the cost of parts (but not return shipping) is 0.00. Please NOTE: As the surface mount electrolytic capacitors age, the rubber seal deteriorates. This creates the condition where electrolyte from the capacitors leaks from the housing onto the pc board and near-by components. The deposited electrolyte may damage the pc traces. We routinely scrub the pc traces with solvent before new caps are installed. Another potential problem we see more often is when the caps have internally shorted burning up small coils and transformers. When the cap shorts a DC voltage is applied across the coil/transformer burning up the extremely fine wires. Our success rate in restoring PRO80's we receive at Kiwa is 85% to 90% due to burned up coils and transformers. Sony replacement parts are not available. Kiwa purchased the last remaining parts years ago. However, at times we do have replacements from.
