Restoration videos

As legend has it, when the Fender Rhodes was switched on, the CS-80 blew up. Part 1 is the autopsy: opening it up to find out what happened, including a dead tone selector. Part 2 brings it back to life and records what was found after the repair, with an honest caveat: there is more work to do, and a detailed inspection is still needed before this CS-80 is fully sorted.
