Why ‘Overhung Filament’?
Overhung filament is extremely difficult to manufacture as a tiny discrepancy in spacing, fixture and material characteristics under extreme temperature can lead to more possible ‘failure’ in production. Overall, tube factory will face a much higher rate of ‘scrap’ even before a tube reaches the product finishing line. This leads to eventually higher overall production cost. Many tube factories deliberately stay away from this filament design.
However, among tube manufacturers and audiophiles it also has a consensus that: A metal plate tube by default will sound more dynamic and transparent than a graphite plate tube; and when the same plate materials are used, a ‘overhung filament’ design by default will sound more delicate and refined than other filament design.
LINLAI 845-DG, 211-DG and 805-DG are made with graphite plate and overhung filament.
Another uniqueness of this ‘overhung filament’ model:
The large graphite plate has 3 side holes to let tube glow out. If you are a fan of 845 tube glowing, this is a great tube to look at while enjoying your tunes!
