I dug out some of my childhood locomotoves this weekend, and one of the ones ive got out was this old Williams GP7 (i think) pair. Ive not run these in 20 years probably. Well the horn sounds absolutely terrible. Is that normal for these? I am not sure that i ever heard the horn as a kid as the horn button on my old transformer was broken, so i legit dont know what it should sound like.
