I’ve restored many antique pianos, and their exquisite craftsmanship always amazes me; both the materials and the workmanship are top-notch. Even more astonishing is that many of these pianos are 100% original and still playable today. My experience tells me to consider the following: 1. Reconstruction refers to removing old parts and replacing them with new ones. 2. Refurbishment (in most cases) refers to repairing existing parts. Upright pianos from the turn of the century to around the 1930s are generally not worth rebuilding (at least in our area). However, I believe a good refurbishment can breathe new life into an old piano, allowing you to enjoy playing it again. You’ll be amazed at how much the tone and performance of a piano can be improved after refurbishment, restoration, tuning, and a complete overhaul.

我修复过许多古董钢琴，它们精湛的工艺总是令我惊叹；无论是材料还是做工都堪称一流。更令人惊讶的是，其中许多钢琴的部件都是100%原装的，而且至今仍然可以演奏。我的经验告诉我，需要考虑以下两点：1. 重建是指拆除旧部件并用新部件替换。2. 翻新（在大多数情况下）是指修复现有部件。从世纪之交到20世纪30年代左右的立式钢琴通常不值得重建（至少在我们这里是这样）。但是，我相信一次好的翻新可以让一架旧钢琴重获新生，让您再次享受演奏的乐趣。您会惊讶于钢琴经过翻新、修复、调音和全面检修后，音色和性能能够得到多么大的提升。
