Yep.
IIRC when Tangent bought up all the Premier designs and assets they kept Paul on board for a while, but when they parted ways Paul had to send all the tooling and remaining spare parts inventory to Tangent.
By the time my 5-25 developed the parallax issue Paul was no longer with Tangent, no longer had any spare parts or tooling on hand, and was unable to help with any possible repairs and said to call Tangent... this was a couple years ago.
At this point if you have a premier and it develops any kind of problem that requires replacement parts, it's either good for a paperweight or as a trade in credit at tangent if it's covered by their warranty. Tangent owns the Premier IP, and now that the legacy spare parts inventory is gone they have no interest in making more replacement parts or servicing the old premier scopes anymore.
I'm sure a motivated person with the right abilities and equipment could reverse engineer and make replacement parts, but it would not be cost effective.
I've got 3 premier 5-25s and 1 3-15, and am keeping my fingers crossed no more of them develop issues. At least the remaining good 2 5-25s and the 3-15 are eligible for full trade in credit with Tangent. Just my luck that the 1 5-25 that died wasn't eligible for any sort of credit...
