Anybody ever tried a bridged T attenuator?

Post by Nigel Tufnel »

Have any of you guys ever fooled with one of this type? I've got some big ass 16ohm 120w power resistors that I use for dummy loads and I have a couple to spare to play with. Just wanted to see if it may be worth buying the associated resistors to mess with it.

Hi Nigel,

About six months ago I built a bridged T attenuator. I put a switch in the circut to go from 12dB to 15dB attenuation. 15dB is too much to be usable. It just kills the tone. I may rewire the circut to 9dB to 12dB.

I loaned the attenuator to my buddy to compare with the other attenuator I built for him. It was based on the usual circut that most people build around here. My friend did not notice an improved sonic quality with the bridged T attenuator. Neither of us spent much time evaluating the experiment.

BTW 120W resistors may be an overkill. Others are free to disagree.
