Remarkably, my piano is playing fine once again. This being my second bout at having to perform rodent damage control, I noticed that any factory electrical tape was undamaged and took this opportunity to wrap other exposed individual wires that lead to the keyboard platform with a nice tight covering of electrical tape before returning them back to their original routing. I then fashioned a metal shield out of thin aluminum flashing that was about 50" long bent at 90 degrees along its length with one dimension 1-5/8" (top) and the other 1-1/8" down. This "armor" was placed on top of the wires leading to the key driver boards that the solenoids plug into. The dimension above allowed it to encapsulate the harness and it secured under the edge of that heavy retainer plate through which the 88 solenoid plunger tips "fire." The 1-1/8" facet slides between the wires and the key pivot block and completes the protection of the harness from all angles of dental attack. Lastly, I closed off the access at the left end of the keyboard with the plastic foam of a "pool noodle" which is similar in shape to plumbing pipe insulation. I had one of these in my garage and it was apparently not on the mouse menu as it was undamaged by them. I removed the wooden end cap and carved the foam to fit precisely so as to block the cavity the end cap created which was used as an access tunnel for pest exploration. The instrument functioned great again and though it is in slight need of a tuning, it sounded fine after the second cocktail. Many thanks for the .PDF of the service manual without which it would not have been possible. Cheers.

The wiring diagrams it contains, a VOM, a soldering iron, and a couple of Saturdays may just sort the fly specs from the pepper in this rat's nest. I rarely shy away from a challenge. Many thanks to the guardian angel that dropped the PDF file my way.
