So I've been testing my M70 all day, sounding GREAT, but when I went to test the cassette player, it had a lot of static, with the VUs pegged at max, faintly could hear the music. Thought i'd clean the heads again, nothing, went through moving all the switches, and found that when I hold the "Rec Mute" button, it sounds crystal clear, and the VU's function properly, and when I release it, back to garbage...
What could cause that button to affect the cassette playback and VU's like that? I've gone through the service manual, but don't know that I see anything related to that. If any ideas I'd greatly appreciate it, I doubt I'll play much cassettes, but it's still important to know.
Thanks!!!
