I've had this tuner hangin' around and put an order in to try out this mod. Here's a link to it http://www.fmtunerinfo.com/DIY.html#KT-5500 I have the caps ordered and will be giving the unit a complete recap. But I have a dumb question on the diodes. "D 6 and D 7 diodes switched to Schottkys" I just took a guess at which schottkys diodes I need. I don't have a schematic and don't know what the original diodes are. I ordered these: http://www.mouser.com/Search/ProductDetail.aspx?R=SB160-Tvirtualkey62110000virtualkey621-SB160-T & http://www.mouser.com/Search/ProductDetail.aspx?R=1N5822virtualkey51120000virtualkey511-1N5822 If anyone has tried this mod or has a recommendation, I'd rather be safe then sorry.
