“KAUN (Pronounced as KA-UN) is probably Yamada’s last super tube amplifier. It represents everything he knows about tube amplication. The cumulative experiences from his entire career, in particular, the fruitful experiences of research and development from Project Chouku 長空, have put forth into the master creation of KAUN 火雲. The size of the amplifier is gigantic with a total weight of 530 pounds. They are in push pull configuration with 4 x 211 tubes per channel. All transformers are FINEMET.”
