HAL-O III brings out the best potential in audio rectifier and power tubes and other sensitive tubes. HAL-O III subdues heater-generated vibrations and common microphonics, allowing a truer rectified current and truer musical signal. Tube output will be a little cleaner sounding, a little more musical, energetic and less vague, while maintaining your system's unique nature and character.
With spring-tempered titanium C-ring and annealed titanium isolation pads, HAL-O III is appropriate for all vacuum tubes, ideal for extremely hot-running tubes, able to handle continuous tube heat in excess of 1000° F (538° C).
With extra-heavy-gauge stainless steel C-ring and four titanium isolation pads, UltraSonic 100 thoroughly tames microphonics in super-giant tubes 3-1/2" to 4-5/8" diameter (89mm to 118mm), including 833, KR T-1610 (Kronzilla), and tubes using T-36 bulb.
