Manufacturer's Description:


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).


Fits miniature 9-pin tubes and all tubes 3/4" to 7/8" diameter (19mm to 22mm), including 10GV8, 12AT7/ECC81, 12AU7/ECC82, 12AX7/ECC83, 12AY7, 12AZ7, 12B4, 12BH7, 12BY7, 12BZ7, 12DW7, 12FQ7, 2C51/396, 396A, 417, 5670, 5687, 5751, 5814, 5842, 5879, 5963, 6072, 6189, 6201, 6267, 6350, 6385, 6414, 6519P, 6688, 6829, 6840, 6900, 6922, 6955, 6973, 6AN8, 6BL8, 6BM8/ECL82, 6BQ5/EL84, 6BQ7, 6BW4, 6C19P, 6CA4, 6C45, 6CG7, 6CS7, 6DE7, 6DJ8/ECC88, 6E5P/6E5PI, 6EJ7, 6EU7, 6FQ7, 6GC7, 6GH8(A), 6GW8, 6H23N, 6H30, 6GU7, 6N1P, 6N30, 6N30P, 6N3P, 6N6(P), 6P1, 6P1P, 6P1P-EV/6II1II-EB, 6S19P, 6U8(A), 6V4, 7025, 7044, 7058, 7062, 7119/E182CC, 7189, 7199, 7308, 7788, 7AU7, 7DJ8, 8416, CCa, D3a, E288CC, E80CC, E80F, E88CC, EC86, ECC189, ECC803/S, ECC81, ECC82, ECC83, ECC85, ECC86, ECC99, ECF80, ECL86, EF184, EF86, EL84, EL86, EM84, EZ80, EZ81, PCC88, PCL82, PCL86, SV83, (T-6 1/2 bulb).
