I was listening to it today for about 2 hours. All of sudden, the sound shut off. I went to the system and saw SP-9 LED turned to green. It was like in mute mode. Then I turned off and turned it back on. The machine seemed working fine, then it shut off again in 5 minutes. What went wrong? Is it the tube or something else? Please help. |

The 555 timer is pretty generic. TI and Fairchild are probably the most popular.

Given the age it might be prudent to replace it if it is an electrolytic. Dave |
