Offering for sale eleven Herbie's HAL-O III-9 tube dampers for 12AU7s, 12AX7s, 6922s et. The titanium HAL-O III dampers are the best tube dampers Herbie's makes and almost certainly among the best (if not the best) available as tube lovers know well.Eleven HAL-O III-9 for 12AU7, 12AX7, 6922 etc tubes - MSRP: $45.75 each For a full list of tubes for which this damper type may be used, please visit the Herbie's link I have provided. I am selling them because I no longer use tube equipment. You should know that you can double or triple up these dampers on your tubes to further improve the damping. As Herbie once explained to me, and since then I learned from personal experience, tube glass vibrations should be damped to the maximum extent possible. Any vibration at all detracts from the sonic performance, so more is better. I don't think these are often available used. Mine are in great condition, and being made of titanium I imagine they are quite difficult to damage so they should last forever. You will be responsible for PayPal and shipping charges. I will also sell these dampers piecemeal for 60% of MSRP for each damper plus shipping and Paypal charges. Please note that there are a total of 23 HAL-O III-9s and 8 of the larger HAL-O III-50s in the picture, most of which are now sold and no longer available. Only eleven HAL-O III-9s are still available. Thanks for looking.
FROM HERBIE'S WEB-SITE:
HAL-O III brings out the best potential in extremely hot-running audio rectifier, power tubes and other sensitive vacuum tubes. HAL‑O III subdues heater-generated vibrations and common microphonics, allowing a truer rectified current and truer amplified signal. A less-fuzzy, cleaner rectified current will typically cause other audio tubes in a component to render the music more clearly. Tube output will be more musical, more 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).
