Spring cleaning…

Although spring is still some way off weather-wise around here, the Easter break certainly gives time for some (much-needed) spring cleaning. We’ve got quite a few official holidays in Denmark already, so with just three extra holidays from your allowance you can get a full 10-day break – nice!

As the weather most of the week turned out to be well-suited for indoor activities (…) this meant I had time to work on getting my “lab” in order and actually start work on some of the various “backlog” projects that my moving uncovered. Highlights worth mentioning 🙂

I mentioned a while ago that I was building an F4 and that is a backlog design that I would really like to finish and try out. I managed to confirm that the boards are working correctly so more or less all that’s left now is to fix a stupid mistake that I made in the (otherwise nearly completed) chassis work.

Another “no-gain” amplifier design is the “MoFo”. As I alluded to in an earlier post I have made my own board which I would also like to finish and test. I’ll be using the smaller 193T chokes as per the build article, so it’s not much power but it should still be an interesting listen. As you can see from the pictures I have the heat sinks sorted, but a few parts are still missing (incl. the chokes). Of course my plan to get the last remaining board parts here in time for Easter did not work when Mouser shipped late, so they should turn up next week instead. But hey, then there’s something to do for next weekend as well 🙂

I also managed to half-finish a couple of new ebay-kit designs, so another Mouser-order is called for to secure the remaining parts. No ETA on either of these, it’s just stuff I bought because I thought they looked like interesting designs.

Last but not least, since I’m not the only one spring cleaning I’ve been keeping my eyes on the local classified sites and picked up a couple of interesting (for me) products that I have been testing. That experience has (once again) convinced me that I am not looking for absolute sound quality, but more an optimal match between the various parts of the system to get the most pleasing result. Maybe a bit contentious for some, but the difference in musical enjoyment is enough to convince me that I am right 😀
