Attenuation

[Coma]

If I were you I'd save my money and spring for something better. The PS1 is tha same model as the Harley Benton Power soak but with a different exterior design. And it's pretty much rubbish. Yes, it'll attenuate but it'll also suck out all the high end of your amp. Even after compensating with the EQ it's going to sound muffled. I tried with both a big 100 w head and a small 15 w lunchbox and the result was the same.

I'd love to get some good information about this- awsell.- My next amp is gonna be 50/100watts- and then I need an attentitatior to reduce the overall volume, for home/practice use .

well I ordered the LPad
and some jacks

I suppose a treble bleed on the LPad will cure the "tone" loss

[beaubrummels]

How did you determine the values for the components, being on the power output stage?

This is a naive question, but...
An LPad isn't a reactive load. Could a cone-less speaker driver (a la Weber MASS) or some kind of transducer/motor/servo/something be added to make it reactive?

(I haven't looked at the internals of my Weber MASS to see what it's design is, just curious if a cheap/easy alternative could be made that is still reactive.)

It's not a load box
it's an attenuation device

The amps speakers will still be connected

The Lpad comes in the 8 ohm variety
I could add an 8 ohm 100 watt resistor to make it 16 ohm

But I'll just connect it to the speaker cabinet that already exists

All I want is my Carvin Belair to be useable at a lower volume

I think if it gets muddy or something
I can always ad a cap across the pad to fix that

[ehdwuld]

So I got my Lpad
took the homemade volume box I was using in the effects loop
And swapped the potp for the pad

Had to relocate the knob
The Lpad was much larger than the pot
So it wouldn't fit the side like the pot did

Works with the Belair great
Had the amp cranked and no bleeding thru or anything

I got one recently and it's far from "rubbish" - it works great.
