I purchased a replacement set of ballasts for my Umnitza DDEs, tested one of them, and it turned out the ballast wasn't the problem. One of the two was never removed from the box. The other was removed and connected but never fully installed (so the sticky tape is still unused). I just hooked it up for a few minutes and found out it wasn't the problem. The only change I made was cutting the black plastic connectors off the end of the wires out to the rings, but you can easily solder or use quick connectors for this ballst and the wires are still plenty long.

$20 shipped... anybody want them?
