| S.Fillipp | Re: Anyone heard of Bogen Amps? You bet! I'll bet three quarters of the small p.a. systems ever installed in schools, churches,and the like used Bogen amps. I used to play in a garage band in high school that used one for an organ amp, of all things. Most of the ones I ever saw were less than 50 watts, but they no doubt made bigger ones. The 70 volt tap is used for distributed speaker systems such as in a school where you have a speaker in every classroom, or lots of small speakers spread around a large room. Each speaker would have a transformer that matched the output of the amp to the speaker. I don't think it was ever used to drive separate amps. This is still pretty much the way that's done - look at most small p.a. mixer/amps intended for this type application, and chances are you'll find a 70V output along with the usual speaker outputs. I don't think this output is of much use otherwise. Schematics...don't know about that - there's an article by Joe Jasniewski that addresses conversion of P.A. and integrated amps into guitar amps at http://www2.aros.net/~tboy/ampage/pa2g.html If you haven't seen it, check it out, it's very informative and has lots of ideas on what to do with this kind of iron. His e-mail address is at the bottom of his article - as many of these types of amps as he has probably seen, he may be of some help. Sounds like fun! Good luck, Steve Fillipp |
