※The hood is missing. TVA-1 is a famous British vacuum tube power amplifier. Equipped with a sturdy, heavy transformer, this is reflected in sound quality. The sound quality is thick and has good extrusion, and the driving power is off par. You can enjoy the attractive vacuum tube sound with the tenacity of the mid-range and the bright mid-high range. ※Since glass fragments are mixed into one bottle of KT88, it makes a rattling sound, but there is no effect on performance. On the exterior, dullness and oxidation can be seen on the chassis (Yonejima Satoshi)
