Gentlemen,
A year ago, I bought used PR99 and I found something strange as below. I believe someone can explain what happens.
1. When I turn on power SW, it plays automatically regardress tape present. Is this normal?
2. 'PAUSE' butten only working when I holding it down while playing music. And playing again when I release it. Is this normal?
3. I could hear hum from monitoring speaker and it actually amplifying by turning volume when playing PR99 without tape set and I pretty sure it still humming when playing music but can't recongnize because of music. Strangely it's not appear from main speaker. Is someone have an experience about this?
Please give me any of your idea or cure.
Thank you in advance.
