Triode vacuum tube amplifier kit, the TRK-3488. Unusually for me, this is a current model. Although it's a kit, the build quality is very high. The appeal of this amplifier is that even beginners can achieve relatively neat wiring. It's interesting how the sound seems better when you build it yourself. The first stage and output tubes are Czechoslovakian-made JJ electronic ECC83S (12AX7) and E34L (EL34), which are quite high-end vacuum tubes these days. The red logo on the Triode amplifier really makes the red tubes pop! Unfortunately, the EL34s didn't face forward... It seems you can also swap the tubes for KT88s, so tube rolling is easy. However, be very careful about selector switch errors, as this is a self-biasing amplifier. All the vacuum tubes are used ones that I purchased. Please check the internal wiring in the images. It also has a selector switch, and it's a bit small and lightweight, making it perfect for those who want to listen to a vacuum tube amplifier for the first time. Rated output: 6W+6W (EL34), 7W+7W (KT88) Size: Width 310 x Depth 280 x Height 190mm Weight: 12kg https://youtu.be/8_cs8TuNrVk?si=6GpDGjegLK0vcP72 As this is a private sale, please refrain from asking for after-sales support or detailed questions.
