and a new refinish ... fill, sand, paint, sand, paint, sand, paint, ... ad infinitum. Not perfect, there are still a few small blamishes but it's far better than it was and I can live with the rest. I also had to dampen the panels in a few places. These ribbons are old and they do buzz and flap a bit down at 30Hz. The dampening did a pretty good job of getting rid of that without harming the rest of the sound.
