Dilvpoetry R50 Vacuum Tube Amplifier with Russian-made Vacuum Tubes

High-quality audio amplifier with vacuum tubes, R50 model

It was in use until recently, so I believe there are no issues with sound output.
It supports both analog and Bluetooth input, and its appeal lies in its ability to create a compact system.

It originally came with Chinese vacuum tubes, but I purchased Russian vacuum tubes separately. The sound became clearer and retained the characteristic warmth of vacuum tubes, making it perfect for those interested in trying out vacuum tubes.

I will include the original 2 Chinese vacuum tubes in the amplifier's box, and the 4 Russian vacuum tubes in a separate box.

The last photo shows an example of its use; I connected it to Dali Spector 1 speakers in my kitchen. Although it wasn't an environment where I could prioritize sound quality due to space constraints and speaker placement, it was very useful as a system could be built with just the amplifier, speakers, and cables.
I think it would be more useful for near-field listening in a kitchen or personal room rather than in a living room.
