S.FillippRe: 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
