I’ve run into a few hurdles with a 4000E I was working on and would appreciate any suggestions.
- LF issue – On one slot, I can’t send to main/quad bus LF. Swapping channels doesn’t move the issue, so it seems slot-related.
- Multitrack 15 – Channel 15 with direct works, but any channel routed to multitrack 15 via the routing matrix gives no output. Looks more like a backplane issue than a channel issue. Haven’t swapped 15 with another yet.
- Noisy pan pots – 3 of them are noisy when turning them. I tried Deoxit F100 through the shaft, but no improvement. Is there any option besides replacing them?
