The new PSVANE 6SN7C HIFI Series sets new standards in resolution, dynamics and also in clean design; to match the clearly reduced high-end design.
The PSVANE 6SN7C is low noise tested (1st choice selection). We are the only PSVANE 6-Star agent in Europe and have 1st access to the top level production quality.

Dimensions (approx.): D (max) = 47mm; h = 96.5mm (without pins)
Note: when used in pairs, a minimum distance of 5mm between the glasses must be observed.

High Polymer Compound Carbon (HPCC) coating is for the first time used on vacuum tube production.

Compared to traditional carbon spray technology, HPCC coating will allow greater concentration of electrons,
enhance and maintain stability of the electron flow, maximize « secondary electron emission surpression » from the glass enclosure,
in turn reduce effects of electron swirl which generates internal noises from the vacuum tube itself.

All Psvane tubes get retested at TAD to ensure the perfect quality even after the long trip from factory to us.

the NEW Psvane MKII T-Series:
Carbon coating inside the glass envelope for better heat dissipation and stability of electron tube performance.

Teflon Base with Oxidized Aluminum Collar:
The MKII series tubes use exquisite Teflon material for the base to improve on low conductivity and stability. The amber color oxidized aluminum collar around the Teflon base is will avoid corrosion as well as finger prints to maintain a prestige appearance.

Psvane logo and serial number
The Psvane logo and serial number are engraved on the base: The Psvane MKII series have its logo and serial number engraved in the tube base facing all in same direction. No print on the glass does disturb the appearance of the beautiful shaped glass envelope.

Glass Quality:
A higher quality glass is used for the MKII series to increase the reliability and stability which does slightly increase the total weight of each tube.

Sound Quality:
The MKII series offers superb sound quality. The new coating materials offer an even better music presentation. Even compared to the great sounding Mark I T-Series you will experience slight 3D imaging improvement, layering and clarity

A completely new production based on the manufacturing technology obtained from Full Music. The development and material composition of the PSVANE 12AT7-S has been specially optimized with the aim of the ideal audio tube. The noticeably improved audio quality compared to regular 12AT7 (= ECC81, 6201) tubes and the
Gold-plated contacts guarantee long-term freedom from corrosion and ideal contact properties.

All parts are selected to the highest standards, assembled only by highly experienced workers.
Suggested break-in persiod is 50-80 hours.

History of 845 tubes:

845 tubes were first introduced by RCA in early 1930s to compete with then industry leader Western Electric. This is also the first 3-element vacuum tube to delivery 60 watts per channel power when used in push-pull circuit design with a manageable physical size. The RCA845 became a milestone of vacuum tube production.

In 1937, Western Electric responded to competition from RCA845 with their newly designed WE284A – which was considered by users to deliver more lively sound than the RCA845 and with very similar electric specifications. WE284A then became the new benchmark of 845 tubes for the entire industry.
However at that time the electronics industry didn’t have many applications for this type of high output power tubes so demand was very limited. Not many WE284A tubes were produced then and even fewer are still around today.

Owning a pair of original Western Electric 284A is a dream for many HiFi audiophiles who own 845 tubes amps, in order to experience what the past glory of tube production could bring to their music system today. However, the scarcity has driven the price to very high level that many audiophiles cannot afford or obtain.

Creation of Psvane WE845:
The Psvane WE845 is a hybrid creation by combining the characteristics of both RCA845 and WE284A tubes. The first Psvane WE845 prototype was sent to Japan in late 2012 for evaluation and the reviewer commented: ‘It’s an ultimate pleasure to re-live the RCA845 sound from Psvane WE845 and I hope you can improve the sound to the WE284A level.’. Psvane design team took another 8 months to improve on design then we come to have today’s final version of the WE845 Replica.
