Hello everyone, I recently purchased a used Touchmaster Delta, I was told whenever I bought it that the Siren/airhorn doesn't work, but that that he hadn't looked into it. I have replaced the 20a interior fuse, and read through everyone else's problems that I can find with no solution thus far. I would really appreciate any help/feedback to get this siren running the way it should. Thanks!

More than likely the output transistors are toast, sorry to say. The blown fuse is the giveaway here. The transistors are less than $4 each, but getting to them is a big p.i.t.a.

Thanks for the reply, any chance you have a lead on where to get said transistors?
