Don't use my 845 amp much anymore, but have always been happy with my Shuguang Black Bottle Treasures from early 2000 tens. Not up on reliability of tubes you mentioned but I've had issues with 101D Linlai Elites and Psvane WE version of this tube, present two Psvane 101 no problems at nearly 300 hours. Grant Fidelity quit carrying these tubes due to reliability issues, Psvane Acme 300B's no issues over around 700 hours. Never had a single Shuguang tube failure in any amp or pre, but then these not premium tubes in most models.
