@stephanurus said in Trumpet won’t play:
I bought a no-brand-name used trumpet at an auction.
OK. You bought a no-brand-name used trumpet at an auction and it doesn't work. Why would anyone buy any trumpet without trying it first? But, don't fret. With a few parts from The Home Depot, you can make a lamp out of it. I did that with a cheap trumpet and it is a great conversation piece. Ollie's sells beautiful lamp shades for $10.
