Orange help, svp
I just got an Orange Overdrive Series Two, model# OR112M  
 
 
 
I would really appreciate an schematic or url where I could find it.  
 
 
 
I have to say that it is my very first valve amp, and allthough I know I  
 
must be very carefull,  
 
I would like to know how to adjust the bias for the power tubes.  
 
It has two very similar variable resistors on the board...  
 
The simpler, the better: something like --> red point of the multimeter  
 
in lug #5 of the first tube... Something like that, if possible.  
 
 
 
Thank you very much.
