UltraSonic Rx-35

Fits standard, straight-sided octals and all tubes approximately 1-5/16" to 1-7/16" diameter (33mm to 36mm), including 5AR4 (Amperex, G.E., Japanese "Mullard" copy, Mullard, JJ, Shuguang), "slim" 6CA7, 6H6, standard 6L6/5881, 6L6B, 6L6WGB, 6SF5 (metal shell), E34LS, medium-diameter EL34 (Philips, JJ, Mullard), EL34B (Shuguang), GZ34 (GE, JJ, Mullard, Raytheon, RCA), KT77.*

UltraSonic Rx Damping Instruments feature perfluoroelastomer O-rings (Kalrez formula 7075) that handle continuous temperature to 600°F (316°C). The firm-yet-compliant O-rings, held in place by homopolymer-modified Teflon pads and tempered titanium C-ring, establish a new acme of audio perfection.

While maintaining the same microdynamic speed, linearity, and detail of Herbie's UltraSonic series, Rx goes a bit further. Besides reducing microphonic anomalies, Rx blends in a subtle contra-vibration that allows a freer musical flow, curing a harsh and stealthy "electronics factor" or "dryness" that ultimately ails even some of the most finely honed audio systems.

A subtly nuanced yet distinct UltraSonic enhancement, Rx is in a league of its own. Your tube gear, no matter how hi-end or how close to sonic perfection, will achieve a fluid, musical potential virtually impossible to achieve until now.

Herbie's top-of-the-line and the world's finest vacuum tube damper, UltraSonic Rx is appropriate for all audio vacuum tubes. Scroll down for size listings, from smallest to largest.
