I had previously replaced the switch on the Dist + and true bypassed it. It came back with power issues. It turned out a wire came loose from the power jack so it was a simple repair.

Loose wire:

Cleaned and tinned everything before any soldering(even the lug at the power jack):

And everything soldered into place:

Moving on to the Phase 90. First thing done was to remove the electrical tape covering the + V wire to the board. I used heat shrink to clean it up.

Here you can see tape on the power plug to isolate it from the enclosure. Not needed so I removed it later.

Here is all of the work done. The LED was positioned on the side of the switch to not mess up the script logo.

Tested and done!!!
