What are offered in the Linlai Tube Amazon store?

Two new factory-direct tube series are offered, ie. ‘Heritage Series’ for high end ‘tube rolling upgrade’, and ‘Aurora Series’ for base level ‘parallel replacement’.

These two series are NOT sold through any other sources including authorized domestic Chinese dealers or overseas resellers. They are exclusively offered through Linlai Tube Factory Official Amazon store ONLY at this time.

Linlai Heritage Series:

It is worthwhile to mention that this new ‘Heritage Series’ is NOT meant to take the place of the Linlai flagship Elite E-series. Heritage series is designed and priced below the Elite E-series, and intend to provide improved affordability to those wish to experience more tube rolling options but hindered by flagship series’ high costs. The streamlined distribution model, i.e no middlemen between tube factory to retail consumer, allows Linlai tube factory to maintain its viable pricing for this ‘tube rolling’ option in the mid-to-high-end market.

At this time, tube models offered under ‘Heritage Series’ are limited to Triode tubes only, i.e. 300B, 2A3, 6SN7 aka CV181, 845, 805A (no cap) and 211.

Linlai Aurora Series:

This ‘parallel replacement’ category of tubes are meant to provide tube audio owners an affordable pricing point as ‘replacement in parallel’ for their aging / failed stock / baseline tubes to keep amplifiers in good operational shape. It provides a ‘different flavor’ of sound, compared to Russian (such Electro Harmonix, Mullard new production) or Eastern European (such as JJ), with a less analytical and more full bodied sound from Chinese origin tube design. If a customer had never experienced Chinese tube sound, it is an excellent starting point to have some fun in ‘tube rolling’ without a big budget.

At this time, tube models under ‘Aurora Series’ include the following:

  • Aurora Series small 9-pin preamp tubes: 12AX7, 12AU7, 12AT7. Please note that Linlai tube factory does not run an in-house 9-pin tube production line. These tubes are procured and screened from the state-owned Shuguang tube factory and re-branded with Linlai quality endorsement. They are further split to two grades – ‘red print without gold pin’ for lower grade and ‘gold print with gold pin’ for higher grade.
  • Aurora Series POWER tubes: 300B, 2A3, 845, 805A (no cap), 211 and KT88 Quad / KT88 Pair.
  • Aurora Series rectifier tube: 274B Pair / 274B Single

Happy tube shopping and thank you for your support for our new initiative!

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.

To avoid confusion: Please note – we are NOT stop PRODUCTION of mid-level series. We are ONLY adjusting distribution method.

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.

Buyer BewareBy admin

Buyer Beware.

Sellers on Aliexpress, eBay, Amazon, or any other marketplace platforms is NOT authorized reseller by [Linlai™ Global] and their tubes were not supplied by [Linlai™ Global].

None of those vendors, including those named themselves such as ‘Linlai Tube Store’ is NOT the Linlai Tube Factory itself. The Linlai Tube Factory does NOT sell directly on any of those platforms.

[Linlai™ Global] do not do forensic research on where those online vendors get their supply, if they are authentic Linlai tubes and what quality they are of. If you are tempted by the low price those vendors are offering and the quality claim they make, you will need to direct your question to those vendors and do your own research.

[Linlai™ Global] will not endorse or confirm quality of Linlai tubes found in the Chinese domestic market, some of which were resold by unauthorized Chinese vendors to overseas market claiming to be of the same quality as the [Linlai™ Global] tubes.

[Linlai™ Global] will NOT respond to inquiries such as ‘is this true and is it identical to your tubes’. Chinese domestic tube market, unfortunately, is very much unregulated with insufficient trademark protection, a very chaotic supply chain dotted by ‘underground or backdoor deals’, sometimes even mixed with counterfeits and bad qualities. We do NOT know all. Our business is to supply quality tubes through our own operation and reseller network. We are not supply chain investigators.

Thanks for your understanding.
