    I have a yamaha ytr-738 that got on e-bay in 2010. The horn was great until about 3 months ago when the valves started turning black and sticking a little bit. Also, the first valve tuning slide has some currosion. What can I do myself to fix this problem? Dell

    Does driving it to a tech count as doing it yourself?

    Maybe you are acidic and need to clean more often. A 738 is from the very early 80's and probably has the YamAlloy valves... notorious for corrosion and sticking.
