Infinite cowbell issue

Hi,

My cowbell -part keeps on playing infinitely, has someone experienced same kind of problems? I'm really crappy at reading schematics, so could someone point me to the envelope section of the cowbell & maybe suggest which components might be at fault? Thank you so much!

Just my 2 cents... I had a similar problem with my 9090 snare drum, turned out there was something wrong in the trigger section. which makes sense, the trigger was always 'open'.

So i would suggest start poking around the trigger section. I don't know if the Yocto designations line up with the original schematics, but take a lot at the picture below; Q1 and Q5 make up the trigger. If you misplaced one of them, that could create your problem. Use a scope or multimeter to check if there is a constant voltage coming from Q5, if that's the case you've found your problem.

I guess this is the answer to "needs more cowbell." Kidding aside, I've had the same problem and it was what Gerbster said. It was a voltage issue that was triggering it.
