This time we try to put power switch and volume control onto the front panel as this may be more convenient for user to control the amplifier. It seems quite nice and we will continue to use this for our new models in the future.

The above solid aluminum knobs are produced by a small factory. The matt silver color was finely made through eletroplate processing.

3 signal inouts should be enough for regular use. The speakers outputs have 4 ohms and 8 ohms options.

These fine quality transformer covers are difficult to find in the market. We fortunately found and bought these transformer covers. They are stretch type covers and have to make expensive moulds and tooling.

I try to use all Full Music tubes, 300B, 274B, 6SN7 and 12AX7 in this amplifier. I can feel the smooth, detailed and refined sound. The quality of Full Music tubes is very high.
