I've been looking for some schematics to build a 100watt power attenuator for my Marshall stack, but I can't seem to find any. I looked in the Pedal Building Thread and still no dice.

If you had a TSL100, you would have that feature inbuilt.

Erm, you will need to get into the guts of your amp to do this - how confident are you with that?
Marshall amplifiers are the truest purveyors of rock and roll known to man.

"And give a man an amplifier and a synthesizer, and he doesn't become whoever, you know. He doesn't become us."

Holy crap, check this out!

Well, I was really hoping to build an attenuator separate from the amp, so that I could change amps without having to build an attenuator into the next amp.

If necessary, I could build one into the amp, though.

Of course. It's easier and lots of aftermarket attenuator are separate. It's very common.

Here's a schematic for a Marshall Power Brake, but i've not seen the guts of one.

I'm sure there are lots of attenuator schematics on the net. You can probably find an easier build than this.

An L-pad is a VERY affordable option, seldom discussed; probably because it's an inexpensive option to big-dollar attenuators. You can get a 100 watt L-pad for less than $20.00. I use a 50 watt, 16 ohm L-pad for my 7 watt (class A, single 12ax7 to EL84 amp) and it doesn't even get warm. Sounds **really** good too!! A 200 watt attenuator sells for about $55.00. I try to have an L-pad with at least 2x the rated power of the amp, or make sure that I keep my master volume/volume away from much past 2 o'clock.
