Musical Fidelity a308CR - amp type??

I recently purchased a used MF a308CR power amp and am quite happy with it! My issue is more with trying to figure out specifically what kind of amp (A, AB,etc.) it is. I have had no luck so far in my searches. I have the owners manual, but it doesn't specifically say. Can anyone shed some light on this for me?? I'm a novice with audiophile gear. Thanks!!
