AR classic 120 schematic

Hello TJ;

thanks for your hint - I searched on the AR website before, but on their website they say there is currently no email available... well, if noone else has a schematic for me, I will try and send them a fax... thought it could be easier to get one here...I also tried several other (AR) schematic sources on the web, but the classic 120 doesn`t appear anywhere...

thanks again,

michael.
