brand new amp, works fine with one speaker and a mic, on the bench, but when attached to the phone system, has distortion, I tried to blame it on the phone co because if I disconnected them it worked ok with one speaker, no there pointing back at me, I need more ammo before I go further, wish I had a spare amp to try out. old amp has blown output ic and one of the two filters popped its lid, I was just wondering if this 70 ohms of resistance was going to be way off base , but apparently doesn't surprise anybody yet, so I'll go a little farther.
