The DEUXamp Final Shots


Here are the final shots of my new steampunk amplifier project… The DEUXamp. A pair of 60-watt mono tube amplifiers, based upon the venerable Dynaco MKIII circuit. These amps use the octal driver circuit upgrade designed by Vacuum Tube Audio, and they sound absolutely fantastic… I highly recommend the upgrade if you are a MKIII owner.

I had originally intended to have brass and copper covers over the transformers, but upon finishing these, I have decided that I really like the contrast of the tubes in front of the black hulking iron behind them! I realize that without those covers they have less of a steampunk aesthetic, but I don’t think I mind that so much. I find that as I travel down this artist’s road, I am constantly changing my ideas of what steampunk means to me; sometimes I think steampunk goes a bit too far into the realm of overly-ornate; Sometimes, less is more.

Who knows though.. I may get a wild hair later on, and decide to build the covers just to satisfy my curiosity, but for the time being I am calling them finished.

Next on the list is the matching speakers, and after those are complete, the pre-amplifier to finish out the set. This has really turned out to be a much larger project than I had intended it to be, but that seems to be the the way these things always go for me.

At any rate.. enjoy the photos!

  1. Mike,

    Terrific craftsmanship! I enjoy looking at these, part woodworking, park metal fabrication. Just all around very clean and simplistic. If you do not mind me asking where within your amp circuit did you tie in your VU meters and did you use a driver board?

    • Hey James!

      Thanks, I had a blast building these.

      The meters on the front of these are tube bias meters for matching the bias on the output tubes.

      There are VU meters on the preamp however, and they are tied right into the input relay board before the volume and balance circuit. They are driven by a driver board that I picked up off of eBay. I read up quite a lot about VU metering before building this, and apparently true VU metering is not a simple thing to achieve, so they act more like signal meters more than anything else, but then, it’s not a recording device so it doesn’t really matter too much anyway. I was just looking for something aesthetically pleasing. 🙂

      Thanks for reading! It’s always nice to see that people actually do come here and look at stuff!
