I recently got hold of a tape deck module using two 990 opamps and two Jensen output transformers. I am now debating whether to build the classic Twin Servo circuit (JLM99 pcb) or two pieces of the Hardy M1 (Mitsos 312 pcb). If I build the Twin Servo I could sell one of the Jensens to finance the correct input transformer, or I can have two channels of the M1 - which is probably excellent sounding, too. Have anyone heard both and is the extra parts count for the Twin Servo worth it?
