Description

Last chance! We only have (1) pair Top 10% Best Grade 845-DG plus (1) single tube now. This model will not be re-stocked going forward. You can purchase them as a Pair (2 tubes), or Pair + Single (3 tubes) as final clearance sale. 

• As this is a clearance AS-IS sale for final stock, no replacement will be available. If 1 of the tubes in an order failed within warranty time, 1/# of the item price will be refunded in lieu of replacement.
• The single tube is matched within 10% with the Pair with emission rating. As the single tube is from a different production batch, its glass enclosure is slightly taller than the pair. The mis-matched tube glass height doesn’t affect tube function and spec matching. As tube glass is transparent and once tubes  installed apart from each other, the height variation is not very noticeable.
• The clearance tubes are tested with excellent emission at 95%+ emission rating.

High end design of  ‘Overhung Filament’ aka ‘hooked filament’:

Overhung filament design is an advanced filament design feature for vacuum tubes, and often only used in high end tube models. As filament is overhung / hooked, it is subject to much less vibration from the tube itself during operation, resulting in a quieter ‘more black’ musical background.

LINLAI 845-DG, 211-DG and 805-DG are made with graphite plate and overhung filament.

The large graphite plate has 3 side holes to enhance heat dissipation without overheating the plates. If you are a fan of 845 tube glowing, this is also a great visual feature to offer ‘warm tube glow’.

Check the tube dimension below – this tube is of a wider diameter that may not fit in certain tube covers (we actually do not recommend using tube covers around the high operating temperature 845 type tubes – most amps’ tube cover can be removed by the end users).
