We may also be interested in purchasing your equipment. Up for sale is ALtec 353A. I have been servicing Altec gear for many years and have developed a deep respect toward all. 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 McIntosh. Please be patient and let's get your little birdy sing again. A favor and replace the most important components that are most likely 90% dead. Power supply caps are those large silver cans mounted on top of the chassis and 1 underneath. This restoration pack will make a huge difference in the sound quality taking into the account everything else works fine. All the parts are of high quality Japanese Nichicon/Panasonic capacitors. I provide several instructions on how to mount those 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. Included in this kit: 1. Power supply stage authentic Japanese Nichicon/Panasonic electrolytic capacitors. 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). Complete audio path upgrade with high quality IC audio film caps. 1 x extra fuse 11. Instructions on how to clean the chassis and the glass.Instructions on how to clean a faceplate 13. Instructions on how to polish knob covers.
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. A full recap of all the PCBs.
