Line Magnetic Tube Amplifier Analog Sound LM129 Pre-amplifier with 6J7

274(5u4)  WE618 Input Transformer 197A Output Transformer

25B and 1126 pre-amplifier are called best pre-amplifiers of WE Company. 25B is designed for broadcast and broadcasting station early by WE Company, which is as large as sound console. The internal part includes components of 130A, 129A and 18A. Considering of volume and practicability of 25B, we recombine 129A and 18A etc. attachments to make them fit to home-use through several years’ research.

Sound of Line Tube Magnetic Amplifier Analog Sound LM-129 pre-amplifier is excellent with sense of nature and reality. We use 4 6J7 tubes to amplify, use 274 (5u4) to be vacuum tube rectification and complement with  1：1 Analog Sound duplicated WE618 input transformer and 197A output transformer. At the same time, we also add switch of input transformer for users to select their favorite timbre.
