1210,00 € – 2218,00 € exc. VAT
300B / 2A3 Single Ended Power Amplifier kit. Full version with enclosure but WITHOUT output transformers. Dedicated for Lundahl output transformers upgrade set.
Description
Directly heated triode tubes like the 300B and 2A3 enjoy an enduring popularity among audiophiles. The 300B with its rich midrange and extended bass – and 2A3 with its delicate expression and gentle tone – they offer a very special sonic experience. These two tubes, similar in appearance but very different in characteristics, can both be used in TU-8900 without any special changes in amplifier settings. Many manufacturers are producing 300B and 2A3 tubes so users can enjoy trying the various versions available in the market.
TU-8900 is a latest addition to the Elekit kits portfolio. It’s a successor of very popular TU-8600 model which, except of perfect sound quality, brings you more interesting features. It offers power tubes rolling (300B / 2A3), possibility to use 12BH7A instead of 12AU7 (ECC82), selectable headphone impedance / volume level, possibility to switch to non NFB circuit and new, polycarbonate tube cage. Together with exceptional kit quality and carefully selected components, it promised a lot of fun assembling and satisfaction with your own, hand-made, very high quality vacuum tube amplifier.
OUTPUT TRANSFORMERS
TU-8900 is available in two versions – with standard output transformers and with dedicated, famous, hand-made Lundahl output transformers for highest possible sound quality. If you decide to buy standard version, it is possible to change them for a Lundahl OPTs later without any problems.
