Make this! It's good

It’s a really good sounding unit. And loved by my family!! The -3db increments are perfect I think. What did you reckon about the eq at high attenuation?

How new is the 125 unit I wonder? I really appreciate JohnH having all this info and testing available. Bloody good mate!!!! I'm using mine all the time. Thanks

Good planning is simply good!

The -3dB switch has been replaced and all is well in the world of Design "M" Attenuators. This circuit is definitely worth building - thanks heaps for all your work JohnH and also for making the development of the circuit available to us! Much appreciated. Really. I mean it!.:agreed: tmingle's...

Hi tmingle, you’re probably already all over the line out circuit but I’ll post this link anyway. Hope it helps someone http://www.dougcircuits.com/lineout.html

Cheers JohnH. I appreciate your kind words. And once again bloody awesome work you’ve done on this. It fills a gap!! I got my resistors from mouser online. Selected for high tolerance and price. Inductors from Speaker Bug. The inductors are listed at 0.33 and 0.52. I didn’t bother to measure...

Yep I should have mentioned it’s an 8 ohm build into 8 ohm cabs. I’ll check through my wiring once more - just in case there’s a fluff up somewhere!! Edit***** Yes I do have a error: the -3dB switch is broken .... I'l fix it today or tomorrow and edit the post above. Those old switches are cool...

Hi Guys, I finished building this attenuator and I've played it through various amps with both single coil and humbuckers. Here's the build: It works incredibly well at getting loud amps down to low volumes - so absolutely YAY!!! Those resistors stayed very cool - the inductors were warmer but...

Got all my bits ..... time to wire it up......give me a while tho!!!!

Ive got and used VVR/power scaling on a couple of my amps for years and years. Here's my 2cents: as an attenuator it is poor because you can get way better sounds with other methods. However it is amazing if it is viewed as a tone tweak at low SPL especially when using the master volume..... try...

Woo Hoo.....very timely schematic JohnH. Thanks

Two of my amps with power scaling / vvr. One has fixed biased and the other cathode biased power stage. Been using for years. I reckon It is best as a tone device really rather than sound pressure reduction. To dial in the sound at higher volumes as opposed to attenuation. Well that is in the...

Could check the connections and lead between the amp and the cab/speakers
