I’m guessing it’s just a simple passive fixed attenuator, using a couple of power resistors.

yep exactly what i mean sorry it took me a minute to respond. i want to try and implement it on an amp im making for myself. the amp i'm building is trying to be a 35w vibroking based more around a super reverb instead of a tweed. and i like micro wattage amps for recording and just playing around at home. so to have an 8 ohm less than a watt speaker out sounds like a fun addition.

Post by: d95err on October 25, 2020, 03:29:20 am: I would get something like a Two-Notes Captor. It’s a great reactive load and has a -20dB speaker out.

It will drop a 50W amp to about 0.5W. Still too loud for most home use though, if you mean to crank the amp.
