SUN AUDIO SV-6V6SE Vacuum Tube Single Stereo Amplifier

Manufacturer: Sun Audio
Type: Power Amplifier (Vacuum Tubes: 6V6)
Output: 4.5W + 4.5W (8Ω)
Dimensions: W360×H270×D190mm, Approx. 17kg
Original Price: ¥95,000 (from 1999 catalog)
This was self-built after purchasing the kit in 2007.
As shown in the photos, there is slight rust forming on the surface of the transformers.
There are signs of use due to age.
The original 6V6 triode tubes are Russian-made, but I also used American-made ones for comparison, so I will include two of them. You can enjoy the difference in sound by simply swapping them out. The circuit diagram is also included.

○Improvements
Input terminals have been added to allow for 2 inputs to the original circuit. (Please refer to the rear panel photo)
The red power indicator lamp has burned out, so I will include a new replacement part.
(The diameter of the new lamp is slightly larger than the original due to incompatible specifications, so the hole will need to be enlarged. However, if the buyer prefers a different color, it might be better to install a lamp with suitable dimensions separately. I have intentionally left it as is.)

○Usage
As this is a power amplifier, it is used by inputting from a CD player and outputting to speakers. The volume is adjusted using separate volume knobs for the left and right channels.
It pairs well with full-range speakers. I used it connected to Tannoy speakers.
I am selling this due to a move.
