-
- The EQ section functions autonomously from the preamp, allowing separate operation.
- A center-chassis mounted tube design effectively isolates heat, preventing interference with other 500 modules in the power rack.
- Swappable tubes offer the ability to achieve diverse sonic variations.
- This amplifier features genuine vacuum tube technology and offers fully adjustable input/output controls.
- Equipped with an 80% nickel output transformer and boasting a clean, attractive layout.
