You local Radio Shack ( I know I know) should have some Piezo horns for less than 5 bucks. The ones I used are 6 - 28 volt DC with a max current I believe was 25 or 30 mA. I did test them by driving them with an FBM39 output - it worked great. But I needed 24V for some relays so I will be powering them with 24V and using a Cout.

Any advice is appreciated. >Thanks. We salvaged the horns from the old Videospec consoles when we tore those out, and use them in a new control room outfitted entirely with WP51Ds. But I bet you're not looking for something along the line of these little 24-volt jobbies, are you?
