Extra rare 310A LCR amplifier with all Langevin. This is used in my system and due of lacking transformer, it is impossible to make a same one. It used 300B tube for regulator electric volt.

All transformers are Langevin, tubes are 310A. Rectifier are 5U4G, 300B, 6AU6 was used for regulator. It makes sound more analog. LCR part is Okamoto Lab made, using all Western Electric parts.
