*The SP terminal was also replaced with one that can be used with bananas. Maintenance was completed by investing a lot of time and money, such as replacing block capacitors, electrolytic capacitors, oil capacitors, etc.! This is the popular A3500. I recommend it to those who want to try out vacuum tube amplifiers for the first time! Of course, the warm sound of the vacuum tube is also there, but the clean, clean sound using the EL34 push-pull is appealing. The exterior, dullness, and small scratches can be seen (Kobayashi Hitoshi)
