- STATUS = Destroyed.
- Controller was wired incorrectly, causing failure of 4 JFETs, capacitors, and multiple resistors.
- Joe P. attempted to replace all damaged components, on powering up repaired board, JFETs failed again.
- Conclusions: More components are damaged than can be seen. Traces may have failed.
- Possible Solution: Ship back to 4QD for repairs. Costs likely outweigh benefits.
- Possible Solution: Purchase new controller.
- New Controller
- Still needs to be purchased. Proposed 4QD UNI.
