    Thông tin thêm: Ampli sử dụng toàn bộ biến áp của hãng Hirata Tango, biến áp xuất ấp XE-20s, các biến áp còn lại được Audio professor đặt hãng Tango làm riêng theo yêu cầu, bóng RCA jan 2a3 gần như mới, bóng tiền 6Z-DH3A mitsushita, rca jan 5z3.

    Các bác tham khảo thông tin tiếng anh bên dưới ạ:

    Morikawa is Japanese master in tube amplifier research, he is author of many famous tube amplifier book, this amplifier was introduced in one of his best seller of serial book named "Audio tube amplifier". Amplifier use all Hirata TANGO transformer, output transformer is XE-20S, which use orient cutting core, same as X series transforme. Block condenser is Audio Professional which is order made from ELNA Cerafine, choke and grid choke, power transformer was Audio Professor Inc, which is special ordered made from Hirata Tango. Another parts are high quality and selected one as you can see in pictures. With XE-20S output transformer you can easily change tube to 300B, as well as PX25, DA30 with some modification. Output speaker terminal are 8,16ohm. Out put power is about 4-5W, 2A3 is working in class A. In this circus, 2A3 was driven by grid choke, which is working same as interstage transformer. It make the sound deeper and wider. It also protect your tube. The prestage is SRPP circus which used 6Z-DH3A tube. This tube is nearly same 76 tube, the outlooking is quite same.
