Unique tube amplifiers crafted with passion and precision
Wb-manufacture offers custom-made tube amplifiers with “No Nonsense” technology, carefully handcrafted in small quantities in Småland, Sweden.
Aurora 20 –
The Glow of True Triode Sound
The Aurora 20 amplifier is a new type of SE amplifier with the Kron Audio T 100 or the legendary tube 845. The amplifier uses an ultra-fast driver circuit with a slew rate greater than 1000V/µsec. Broadband c-core transformers with ultra high bandwith are used in the output stage. The power tube is a power triode T-100 handmade in Prague by Kron Audio. The output power is 2 x 20W with a distortion factor of 3%. The amplifier is available only as a power amplifier. Mono versions in bridge circuit with double output power are available on request.

Medusa 55 – The Power of Perfect Balance
The Medusa 55- amplifier is a fully balanced tube amplifier, which can be equipped with different power tubes on customer request. The following tube types are available: KT66, KT88, KT120, KT150, with the output power remaining essentially the same, only the damping factor and Class A range changing.
Our preference for this amplifier is the excellent handmade KT88 tube from Kron Audio in Prague.
The Medusa 55 amplifier combines the classic „split load design“ of the legendary Mc Intosh and Quad amplifiers with the latest semiconductor technology and special toroidal transformers of the highest bandwidth. Carefully designed control circuitry provides automatic bias adjustment of the power tubes and easy tube replacement just in case.
The amplifier operates with almost no negative feedback for an open and dynamic sound image.
The Medusa 55 amplifier can be designed as a power amplifier as well as an integrated amplifier on request. Mono versions in bridge circuit with double output power are also possible.

Medea – The Essence of Signal Purity
The Medea is a universal tube preamplifier, which can be configured according to customer‘s requirements.
The preamplifier uses the long life tube D3a as impedance converter for low distortion and very low output impedance.
The output impedance is typically 50 ohms, so longer cables are no problem. Standard 3 line inputs and one high quality MC input are available. The RIAA equalization is designed with an ultra low noise discrete transistor amplifier, the active signal amplification is designed in tube technology. If desired, the RIAA equalization can also be performed via a passive LC filter, here too the coils can be implemented in silver alloy or pure silver winding. The MC input can be configured to MM or MI if desired.

Aurora 20 MK II – The Evolution of True Triode Sound
The Aurora 20 amplifier is a new type of SE amplifier with the legendary tube 845. The amplifier uses an ultra-fast driver circuit with a slew rate greater than 1000V/µsec. Broadband c-core transformers with ultra high bandwith are used in the output stage. The output power is 2 x 20W with a distortion factor of 3%.
The amplifier is available only as a power amplifier. Mono versions in bridge circuit with double output power are available on request.

Minerva – The Apex of Single-Ended Power
The Minerva amplifier is the summit of the SE amplifiers and uses the high performance 304TL triode as the output tube. This amplifier was designed at the customer’s request and utilises the driver circuitry proven in the Aurora and uses special output transformers with high bandwidth. The output power is 1 x 50W in pure class A. The distortion factor is 3%.
This amplifier is only available as a pure power amplifier in monoblock version.

Gaia – The Universe of Single-Ended Power
We have written the story of Minerva further and the result at the end of the road has become our super single ended amplifier Gaia. A stereo output stage with external power supply and the probably biggest and best audio
triode ever: the legendary T 1610 „Kronzilla“ tube. A new driver circuit has been designed that connects tubes
directly without coupling capacitor and thus we can drive up to class A2 for powerful impulses. Experience a new
world of sound: raw power if needed but at the same time a musical river in which the finest micro details come out. Enjoy music and dive into Gaia‘s sound universe.

Medusa Wood – The Enchantment of Balanced Sound
So many instruments are made of wood and we believe that wood is a musical material. Therefore, we have invested quite a lot of time in developing a new enclosure that consists in large parts of wood. The end result is a new series of our amplifier ‘Medusa’, namely Medusa Wood. You can choose between almost a hundred different veneers and between different anodised colours, you can decide on the power tubes used and we will build your dream amplifier according to your wishes. The technology is unchanged from the Medusa, a fully symmetrical design with 2 drive circuits and an impedance converter that drives power tubes through low resistance and high bandwidth.
Let yourself be enchanted by our new Medusa Series!
