For sale: my wonderful Herbie’s Audio Lab tube dampers as listed below.
I’m the original owner of the Herbie’s products. The products are in excellent operating and cosmetic condition and are rated 9/10 on the Audiogon scale. The products were used in a smoke-free, pet-free, and child-free dedicated music/home theater room.
I’m downsizing my stereo from tube separates to a solid state integrated amplifier due to my recent retirement and changing living circumstances. Consequently, I have many Herbie’s products that are no longer needed in my downsized stereo.
The Herbie’s products come in their original packaging complete with owner’s manual (except as noted below) and will be carefully packed for shipment.
The Ultrasonic tube dampers have titanium C-rings; the other tube dampers have C-ring materials as noted below. Please see Herbie’s Audio Lab website for a full description of Herbie’s products and applications.
