3. Disconnect the RCA cables going to your amp and connect a home CD player or a portable player with RCA outs, and see if you get any music from the speakers, to make sure the problem is not downstream from the MS-8.
1. definitely using RCA outs (same side as speaker outs)

2. I think I'm alright on this one. As previously mentioned, speaker-level outs from the MS-8 read around 2.5V. You got readings on 0.02V. Others on the web list anything from 0.2-4V. I get . . . 0. True, my meter may not pick up 0.02 if that is the case.

3. on a friend's advice I ran a stripped RCA (center wire to +, outer to -) from RCA outs 1 and then 3 to a speaker, running 300 and 63Hz test tones at about 45 clicks, respectively. Heard no noise.

Ugh. Thanks for your patience.
