<html>  <head></head> <body>  <DIV>List,</DIV> <DIV>Does anyone know if Yamaha spinets ca:1967 or so , had upper row of plate bolts secured with acorn nuts at the back of the piano? Looked like a separation repair, but the owner said it was purchased new. Also ,don't the nuts go on the inside of the piano in a repair like this?</DIV> <DIV>Any, piano was about 40cents down in pitch ,with some very out unisons, baseboard heating up against the back.</DIV> <DIV>My real question relates to the plate nuts which were sooo loose I could tighten them by hand. I used a socket wrench to torque them down, but should I be doing anything else before bringing up to pitch?</DIV> <DIV>Thanks,</DIV> <DIV>RU/UP</DIV>  </body> </html>
