Pilot AA-903 restoration kit service recap capacitor rebuild filter capacitor
We may also be interested in purchasing your equipment… This listing is for 1 x FULL kit. Up for sale is Pilot AA-903 restoration kit. ———- The scarcity of good, honest techs who can do good and reasonably priced restoration/rebuild of audio equipment (especially tube gear) made me start offering this restoration kit.In today’s day and age it is very hard to come by a knowledgeable tech who can service your audio gear well. I have seen many poor quality restorations of equipment that cost way too much to its owners.In 99% of the cases there were only few parts replaced, instead of a full and proper restoration job. On the other hand, if one succeeds in finding a good tech, a wait time is usually 6-12 months for the unit to be serviced and costs is sky-high!!! In this kit I offer parts and instructions for a full/complete restoration of your audio equipment. I have been servicing audio equipment for many years and have developed deep respect toward all good equipment, especially tube gear. I really do think they sound amazing if properly restored. I have seen many bad quality restorations/fix jobs done to these units that made them sound cheap and very low quality. Knowing how amazing and warm these units can sound, I have decided to develop this kit to help you do a great job on your equipment. It includes very good upgrades and improvements that MUST be done to the unit. Please do your audio equipment a favor and replace the most important components that are most likely 90% dead. Power / Filter stage caps are those large silver cans mounted on top of the chassis and sometimes underneath. This restoration pack will make a huge difference in the sound quality. All the parts are of high quality Japanese Nichicon / Panasonic / IC / United Chemi capacitors. I provide several instructions on how to mount those new electrolytic caps. The best one is to rebuild those original cans. You will receive a step-by-step instructions and all the proper caps needed for that. This technique will keep the original look of the unit. I am extremely particular about the quality of the parts provided with this kit. Knowing how many bogus/fake caps, diodes, resistors etc. out there, I source all the parts from reputable whole-sellers and buy them in bulk. The knowledge that I am going to share with you have been acquired by me over many years serving audio equipment. Please be patient and let’s get your little birdy sing again. “They Shall Have Music” Avery FisherIncluded in this kit: 1. Power/Filter stage upgrade with authentic Nichicon / Panasonic / IC / United Chemi electrolytic capacitors. 2. Detailed instruction with colorful images, schematics, manuals (all of these are in electronic form, I consider these much better than printed version due to zoom availability). 3. Schematics 4. Complete audio path upgrade with high quality US made (IC) or Panasonic audio grade film capacitors. 5. Parts for compete recap of all the electrolytic capacitors. 6. Complete recap of all oil, film, paper, lytic caps. 7. Inrush thermistor (to limit the initial current inflow). 8. Transistors (PNP, NPN). 9. Instructions on how to clean the chassis and the glass. 10. Instructions on how to clean a faceplate 11. Instructions on how to polish knob covers. 12. Support/help to a reasonable extend in case you need it. (This is what makes us different from other sellers.)——–Also available NEW production volume control ———–> LINK We may also be interested in purchasing your equipment… PCBs. requires a full recap of all the PCBs.
