The A2500 is a tube type power amplifier kit that has been replaced with speaker terminals that are easy to use even for beginners. 6AQ8 for the first stage and 12AU7 for the phase reversal stage both use triodes. Since triodes are used across all stages, the sound is taut and bright, with excellent nude characteristics. The exterior has dullness over time, rust, and small scratches.
