Antique Sound Lab Hurricane DT
A monoblock tube power amplifier using KT88 tubes, capable of 200W in pentode mode with dual-mono point-to-point construction.
Overview
The Antique Sound Lab Hurricane DT is a monoblock tube power amplifier built for high output and reliability in demanding audio systems. Manufactured by Antique Sound Lab, it delivers up to 200 watts per channel in pentode mode and switches to 100 watts in triode mode, making it adaptable for different sonic preferences. It uses eight KT88 output tubes per unit and features true dual-mono construction, ensuring channel separation and structural independence. Designed with robust materials, each amplifier has a stainless steel chassis, an anodized black front panel, and a chrome top surface. Weighing 70 pounds each, these amplifiers are substantial in both build and sonic presence.

Design
The Hurricane DT uses a circuit topology that supports both pentode and triode operation, allowing users to switch between higher power and a more nuanced triode sound. It is built with true dual-mono construction, meaning each channel operates independently without shared circuitry. The internal layout relies on point-to-point wiring, a traditional method valued for durability and signal integrity. Bias adjustment is accessible via setscrews, facilitating maintenance.
Reception & Use
The Hurricane DT is praised for its powerful, dynamic, and engaging sound, with strong bass control, wide soundstage, and excellent ambience retrieval. It handles difficult speaker loads and lower impedance speakers effectively. Some units exhibit a low-level hum, audible only when near the speaker, and bias drift may occur over time, requiring periodic adjustment. The stock Chinese KT88 tubes are often replaced by owners to improve performance and longevity.
Market
Current market prices for the Hurricane DT vary widely, ranging from $1,495 to $5,000 per pair, depending on condition and modifications. Units upgraded by third parties, such as Response Audio, typically command higher prices. Common issues include blown fuses or resistors on initial use, but the amplifier is generally considered reliable and easy to service. Bias drift and tube replacement are routine maintenance considerations.
