I want to provide a few months update on how the Tower of Terror is doing as of recently, nothing really major, but noteworthy changes.
Starting with the show shafts, the burnt out ambient lights in the hallway scene for all shafts has been fixed(although it is noticeable which ones as they are brighter/less orange) from the "reopening incident" where the ride system was sending too much voltage to the lights.
The starfield doors on Echo side are finally working again, but now they open up a few seconds earlier than before. I have a suspicion that before they were disabled, one side was not opening fast enough and could of made contact with the AGV vehicle, so for a temporary workaround, they made it open up early.
Next up is the drop shafts, which there is plenty to talk about. The drop shaft speakers are finally working again on Echo side, so the drop sequence audio is pretty much the same now between Foxtrot and Echo(Echo does seem like it has louder VVC speakers though). It is still quieter than in early 2019 though. The 7th Horton doors on Echo have been on/off as of recent, but as of recent, all of the Horton doors on Foxtrot are working again!
Now moving onto the not-so-good changes. The secondary strobes(not the main camera strobes) on the external sign facing the doors have been disabled again, I am not sure if this is in preparation for the 50th anniversary look, or another reason why. The bigger change is that Echo now closely matches Foxtrot with the delay between the drop sequence audio and movement, where Echo is now more delayed by an additional 1-2 seconds behind the audio. Again, I am not sure if they are doing this in part of a fix for both sides to get rid of the delay entirely(seems odd they would go in this direction for that), but it is kind of suspicious that it happened at the same time Disney put the Photopass logo over the ride photos.
Everything else is the same.
