I have had tinitus and nerve damage to my ears most of my life and consequently and necessaraly have to keep SPL kind of under control on the low DB side. For years I used a Tom Scholz Power soak to keep amps burning and sound under my control. A lot of attenuators have come on the market since those dark ages of the early eighties, so I thought I'd start a thread on them. I've been mentioning them in other posts and gotten a Weber Mass recommended to me. Attenuators https://taweber.powweb.com/weber/mass.htm Some wise words from the Weber site: "You should select an attenuator that can handle at least as much power as your amp puts out. Amplifiers are generally designed to operate clean, and most manufacturers specify the output power as clean power. When you run the amp full blast, the output devices actually become more efficient because distortion is not considered. Under those conditions, the amp may be capable of putting out as much as 50% more power than its rated clean power. Be aware of that when choosing an attenuator, because the idea of using an attenuator is to run the amp full blast into power tube distortion and then controlling the level going to the speaker. If you are going to dime a 50 watt amp, you should choose a 100 watt attenuator." I'm looking into the THD Hot Plates too, since they seem to be at the checkouts of all the music stores I frequent. THD Electronics THD Hot Plate Attenuator: Harmony Central User Reviews I found a great site for links and technical bits about attenuators: Adam's Amplifiers: Attenuation Anyway, thought I'd post some pics and links in case anyone is thinking of turning it down a tad and actually hearing in their old age The THD and Webers have the added benefit of creating a very usable line out AFTER the tube amp stage! How cool is that? I like attenuators, even though they do not reproduce exactly the tone of a dimed amp and speaker cab. They are a tool and good ones still keep gobs of tone. I wish more amp designers had attenuators built into their chassis. I'd pay a bit more for that on an amp. A good design would have a pure bypass for the tonal purists out there and the times we don't need the attenuator. Granted it helps bake and shorten tube life, but that's part of the tube game, innit?
