Product Description

Experience the Warmth of Pure Tube Sound

Elevate your home audio system with the R8 Tube Integrated Amplifier. Masterfully handcrafted with point-to-point scaffolding welding, this amplifier combines vintage engineering with modern performance upgrades. The R8 is designed for the discerning audiophile who demands power, clarity, and the lush, immersive soundstage that only vacuum tubes can deliver.

Core Features & Build Quality:

Flexible Tube Configuration: Features a robust output stage utilizing four KT88, 6550, or EL34 tubes (factory installed KT88). It uses two pairs of 6SL7 and 6SN7 tubes for voltage amplification and driving, allowing for easy tube rolling and sound customization.
High-Fidelity Performance: Delivers 45W + 45W RMS in Ultra-Linear mode or 23W + 23W in Triode mode. The frequency response of 12Hz-40KHz ensures deep bass and crystalline highs.
Premium Engineering: Equipped with a custom square power transformer and wideband EI output transformers. Features an independent BIAS-ADJ current display for easy monitoring and maintenance.
Pure Signal Path: Utilizes thick silver-plated signal leads to minimize signal loss and preserve audio purity. Includes a specialized 6SN7 for power supply filtering to reduce noise.
Operational Versatility: Switch between Triode and Ultra-Linear modes to suit your listening preference. The pure post-stage function allows for connection to an independent preamplifier.
