ขาย Integrated Amp ยี่ห้อ Sansui รุ่น AU-D907 (Made in Japan) ราคา 13,000บาท

ไฟ 100Volts ***มีหม้อแปลง 100Volts ขาย กรุณาโทรสอบถาม***

 

ตัวถังเหล็ก หายากมากๆ

 

กำลังขับ 100W + 100W @ 8 Ohms

 

หม้อแปลงมีถึง 2 ลูก ลูกนึงเป็นชนิด Terroidal อีกลูกเป็น EI

 

ทรานซิลเตอร์ชนิดจานบิน

 

โครงสร้างวงจร จำลองมาจากรุ่น Top คือ AU-X1
