I can provide you a PDF file that includes the notes and a crossover schematic documenting the mods that I made to my Leak 3090s, however it exceeds the size of file I can upload. The notes are handwritten because they were generated in 1982 and 1983 before I had my first home computer system. I would expect most of the capacitors in your crossovers are out of tolerance and some are degraded or worse. In addition to the capacitors I had planned at one time to upgrade the inductors and power resistors, but my 3090s became secondary speakers so I never completed those changes. If you can PM me a direct email address, and information on what size of attachments you can receive I will forward you additional Leak 3090 information.
