Only one was made. Preamp with phono amp stage, output transformer is Extra rare 30s year Thordarson output transformers. Sound is nearly same as Western style sound.

This one is only one because it is impossible to get the same output transformers as well as filter condensers that using in amp. You can order the nearly same one but with another output transformers. If you saw that this one was sold out, price for same one with another output transformer is 2850USD without tubes.

Voltage regulator is 6V6 and 6DJ8, Rectifier tube is GZ-34(5R4GW, 5AR4, 5U4). I include all tubes.
