Did any of these analog tone generators come with the newer style amplifiers? There's this one ASC Alertronic in Kodiak, Alaska that has a dual tone analog controller, but with virtually no distortion of the signal at all. Compared to the ACA Alertronic that was in Rolling Meadows, it sounds like a much newer and "cripser" sounding siren.
Always loved these dual toned ACA Alertronics. Sound way better than most FS MCPs out there. And you had mentioned that a lot of the drivers you have in the siren were burnt up. You should try getting some stereo horn drivers from a Radioshack or electronics store. They should last you quite a long time as long as you don't get any that were made in China. Try some BlastKing USA 1000 watt drivers.
