| Heathkit IO-12 Loose wire |
| (1/1) |
| Davemiller1985:
hi, i recently got this heathkit IO-12 from my father and was cleaning the pots when i noticed a wire had come loose. it is a black wire coming from the horizontal gain knob. i do not know where i can find this on the diagram or where it may go. i have attached 3 pictures in hopes that someone can help me. i have also attached a diagram of the area nearby the pot and the whole diagram. edit: i have learned that this device has been open possibly multiple times as it came from a school/college. |

Difficult to see, but I think the wire is coming from the counter-clockwise (CC) end of the Horizontan Gain. In which case it should go to ground - 0V. It might have been connected to the chassis. |

there is a red wire attached to the same point which goes to ground. sorry about the quality, im using my laptop |
