The other thing that's kind of cool about the amp modules is the ease in switching form bridged to stereo mode. If it turns out that the M80 impedance is too low (it does seem to dip to 3 ohm) and the amp starts to overheat or cut out, I can always unbridge the amps by just changing a jumper and wiring the output from +V/+V on each amp, to +V/-V on each channel of the amp. I'd still have tons of power at 250W per channel, and now have 4 channels so I can also power the VP180 with it (and have 1 channel left over). It's a fallback position just in case.

HA! Now that's a random place to have such a sticker.

Good luck with everything Steve, this is really cool!

That amp is certainly impressive. I've always wanted to do a DIY tube amp or DAC. However, this should be a perfect pairing for the M80's, you'll really be able to rock the house!

As always, remember that we love pictures smile

From what I can tell, if you want to make it pretty, you have to solder. If you just want to try it out, you can just screw the wires into the posts.

Exactly what I was wondering. My guess is you do ALL the build/soldering although the website infers that most of it's pre-built. What's the scoop, Steve?

Apparently you just wire it together. Source

Since this amp seems very simple to put together, if you really wanted to go DIY you could do component upgrades. Most of the time they are transformer or capacitor upgrades. Some believe that component upgrades can push "cheap" equipment with good circuitry designs into something that's great. Tried looking up mods for this amp, couldn't find much.

Class D amps don't take to tinkering with their designs too well. You really need to know what you're doing before you substitute any component. Else you end up building yourself a 1000 Watt AM radio station.

Sorry guys, I was out of town on business... Just got back and the box from ClassD was waiting for me! Quick shipping indeed! The toroidal transformer is coming directly from the manufacturer, so I hope it comes soon. I'll start mounting and wiring what I have so far tonight. Here's a couple of pix:

PS - The ruler is there for TomTuttle... Sense of scale.
