You can tell if the bellowsw leak by pushing them without pressing a key down. If the bellow close easy, you probably have an air leak. You do not need to push very hard.

The loudness should be about the same on push or pull.

Also check the thumb air valve.

Let us know what you find.

I took it back. I think I will get a large bottle and start putting my coins in there for a nice one.

Thanks for your help.
