About me

The WB Manufacture

stands for individual tube amplifiers in "No Nonsense" technology, carefully handmade in small quantities in Småland Sweden. We do not use hand-wound capacitors and unidirectional silver wire in our devices, but selected, best industrial quality and carefully designed and measured circuits. All our push-pull amplifiers feature a fully symmetrical circuit design with true differential amplifiers; the single ended amplifiers a specially designed solid state driver stage. Only when the amplifiers convince metrologically, the first listening tests take place at our company. In the circuit design, the focus is on large bandwidth and simultaneously low distortion even without negative feedback. Negative feedback is only used to a small extent in our devices to achieve optimum channel equality. The negative feedback factor is a maximum of 6dB, while the power bandwidth for the push-pull amplifiers is over 100kHz.

Let us manufacture your desired amplifier for you. Every amplifier is individual: You choose the right amplifier in our studio, which will then be manufactured exclusively for you. You have the choice between different technologies, housings, different output transformers and different tube configurations. You still have a quartet of NOS tubes in your basement? No problem, we will build the matching amplifier for you.  And the best: We grant 5 years warranty on the electronics of the amplifiers, on the tubes the usual 6 months. We can check and repair most of the tube units ever built. After repair we provide a warrenty of 12 months.
