In Reply to: MM phono stage hum posted by DanK tubes on February 28, 2007 at 09:20:00:
Aside from the scope issue, the hum at the MM stage is 60hz? I assume you're using DC heaters? Have you tried putting a bias voltage on the heater? I know phono stages are very sensitive to grounding schemes. You have looked for ground loops? Using a star ground?
