My Audio System

Main system This is the main audio system in the bed room of the second floor. I normally select one amplifier from three individual ones, 1626 all-stage differential push-pull amplifier, 40KG6A push-pull amplifier, 211 single-ended amplifier. The input of amplifier is changed by the switch equipped in 6DJ8 preamplifier. The tuner is SONY ST-S333ESG, the CD player is SONY CDP-X55ES, and the speaker is hand-made one with JBL speaker units, they are all used equipment.

If you put the mouse over the image, it will be enlarged. (Same below)
