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. It puts out up to 200 watts per channel in pentode mode and 100 watts in triode mode. Each unit uses eight KT88 output tubes and true dual-mono construction, so the channels stay separate and independent. The chassis is stainless steel, the front panel is anodized black, and the top surface is chrome. Each amplifier weighs 70 pounds.

Design
The circuit supports both pentode and triode operation. Pentode gives you the higher power, and triode gives a more nuanced sound. Because it is true dual-mono, each channel runs without any shared circuitry. The internal layout is point-to-point wiring, a traditional method valued for durability and signal integrity. Bias is adjusted through setscrews, which makes maintenance easier.
Reception & Use
Reviewers praise the Hurricane DT for a powerful, dynamic, engaging sound, with strong bass control, a wide soundstage and excellent ambience retrieval. It handles difficult speaker loads and lower impedance speakers well. Some units have a low-level hum, audible only when you stand near the speaker. Bias can drift over time, so it needs periodic adjustment. Owners often replace the stock Chinese KT88 tubes to improve performance and longevity.
Market
Current market prices for the Hurricane DT vary widely, 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. Blown fuses or resistors on first use are a common issue. Even so, the amplifier is generally considered reliable and easy to service. Bias drift and tube replacement are routine maintenance.
