For me, valve amplifiers and some solid state exhibit the 50% rule. Amps sound at their best at or around 50% of their rated output to my ears. Just on the verge of breaking up. Dig in hard, they crunch, ease back and they sing and purr. There is however, a major problem with that. Volume. Even a 5 watt amplifier can be way too much in a small room. Some manufacturers have biasing schemes, or pentode/triode switches, or switch-able B+. These are often not wholly satisfactory. Valves behave differently with different voltages/configurations. Power amplifier stage distortion and compression differs from pre amp overdrive, and driving the power stage is the only way to go. Most attenuators on the market seem to offer fixed impedance. Buy an 8ohm to match the 8ohm transformer, a 16ohm for ... you get the picture. The Jet City, sorry, Harley Benton attenuator offers 4,8 and 16 Ohm loads, so can be used for cabinet matching too. That alone is worth it. The attenuator is an L-Pad type. The actual pad itself is nearly half the cost of the whole unit. Added to that are some large wirewound resistors which work in parallel with the pad to convert the loudspeaker signal to heat. There is a discrepancy in sound between full power amp into speakers and full power amp into speakers via the attenuator. A large part of that is the lack of air movement. In terms of taint of the sound though, this is a good unit. Far far far, hugely superior to a mesa cab clone in my direct experience for the cab sound. This unit retains clarity, the cab clone made the signal at the cab sound woofly. I can go from silent to near full volume whilst the amp is running constantly in its region of sonic bliss. There is a mic sim and line out, and this is where this unit fails laughably. The pickup seems to be -after- attenuation. What possible use is that. D'Oh! on a large scale. Pickup from the input side and pad the signal if need be is the best way, and thanks to an odd decision ( it may be a valid reason, if so, I'd love to hear it ) on the part of the designers, that's what I do. I use a D.I inline before the attenuator and it works beautifully.
Odd design decisions aside, the micsim could be used in a live situation where you want to go front of house and have to keep sound levels down. This is becoming common unfortunately. Still, at least smaller amps are cheaper to buy and run.
Overall then, this is a bargain. Forget the line out and micsim. They're not that good or indeed for home use that useful. Use it as an attenuator that is substantially cheaper than most, and usefully cheaper than the unit it so resembles and you'll be happy. Bargain, and a wise purchase for neighbourhood harmony.
Great device to make your tube amp play with bedroom volume.
Great device to make your tube amp play with bedroom volume. I?m using HB Power Attenuator with Fender Hot Rod Deluxe II Combo and I think it is great. The only thing I need to make it work is new cable from speaker to Attenuator. This modification can be rolled back in a minute so it?s cool. For cennection to the amp you already have Jack output. Thanks to this device I can make my combo play good providing more power to tubes and make it quiet without losing sound. My neighbors are happy now ;) About the line output it doesn?t sound good without a speaker so if you want to use it for recording you will probably need some speaker emulator.
