just got a free pioneer sa960 amplifier.....want to wire it to my current receiver, sherwood ra1140.....however i do not think i have the right terminals to do so. on the receiver i have phono, CD, video/aux, tape (play and record). on the pioneer i have phono, tuner, cd/video, tape 1 (record and play), adapter/tape 2 (out and in). any suggestions?
