Linlai tube factory is working on re-structuring the product line and fulfillment strategies for 2026, to better manage and offset global tax and tariffs impacts.
The Flagship Elite Series and Western Electric (WE) series will remain unchanged, with hand picked Top 10% Best Grade tubes continue to be available to our most high end customers. Value shoppers who have more relaxed expectations on tube measurements can also obtain our Factory graded Elite Series and WE Series tubes too, at slightly lower price compared to the Top Grade tubes.
Mid-level Series (namely DG-Series, Sapphire (blue bottle) series, Dream Series, ZX (grey bottle) Series, T2 (black bottle & clear bottle) series going forward in 2026 will NO LONGER be graded after Factory QC tests. These series of tubes will be only available by ‘random inventory pick’ as ‘Factory QC Pass Grade’ going forward.
The Entry Level HiFi series will continue to be offered in wholesale quantity to worldwide tube amplifier brands, to keep their new amplifier products affordable in their base tube configuration.
Right now is the LAST OPPORTUNITY for customers to acquire our pre-selected ‘Top 10% Best Grade’ Mid-level series of tubes listed below.
