This time I am listing a Yamaha full double horn, model YHR-661. The key change is in B♭. This is Yamaha's first professional model and was Yamaha's top-of-the-line instrument at the time. I was considering listing it after repair, as you can see from its condition, but I thought there might be someone who could use it as is, so I am listing it now. In the used market, it is traded for 130,000 to 150,000 yen, but this time I have set the price as a junk item. Therefore, price negotiations are welcome. If you would like a repair, please write it in the comments, and I will accommodate you, although the repair fee will be added. In that case, I will propose several options. Regarding the condition, the tuning slides are not stuck, and the rotary valves are working. However, the solder has come off in three places (photos 7 and 8). Also, the brace on the mouthpiece pipe is worn. Fortunately, it doesn't seem to have corroded the mouthpiece pipe itself (photo 10). When a professional player played it, they said it was an instrument that could still be played and would be usable for a long time if repaired. In addition to normal use, it can also be used for parts since it is no longer in production, and those with experience or those learning repair may try to fix it themselves. Although it is in this condition, since there have been many cases of item swapping recently, I basically ask for no returns or exchanges. Thank you for your understanding. P.S. Due to a mistake, I took the photos with the YHR-662 case, and I have retaken them with the original YHR-661 case (photos 13-14). As an apology, I will lower the price by 10,000 yen. Thank you.
