I started this page just to document the MayBALD circuit coming together into a common enclosure along with the amplifier interconnects and a VFD to display . Originally this was falling into the Maylume page, but I decided to move anything dealing with the enclosure to its own spot as it is a project on its own, and since I decided to put a hold on the Maylume project.
The rear panel will look something like this:

I've placed the power supplies in the enclosure, and the MayBALD driver circuit as well. The supplies are wired and output +/-15VDC. Check out the pictures below. Yes the wiring right now is a bit messy and needs to be cleaned up before the project is completed.

Finished milling (if you can call it that) the holes out of the backpanel for the additional RCA jacks that are to be added. Basically installed them all, I just need to tighten them in. You can tell it is a total DIY job as I don't have a nice drill press, or milling machine, and the DIN connector holes I reemed and filed out as I didn't have a proper size drill bit. But in the end, it will all be functional. Below are the picks of that and the MayBALD all wired. View the MayBALD page for more pics.

I've finished off the enclosure. My ideas for it changed from when I first envisioned as to what I would do with it. It was originally going to be used for a 2 channel Gainclone amplifier, then it was to house the MayBALD and Maylume circuits. Though I finished the MayBALD (as pictured above), I dropped the Maylume part way through completion. I did have part of the Maylume built so I decided to use what I could from the circuit...mainly the 5V regulator (LM7805). This regulates the +15VDC to 5VDC that is used to power a VFD (Vacuum Floresent Display). The parallel port that was to be used for interfacing the Maylume to the computer is now used to interface to the VFD instead. The VFD is a simple parallel port type based on the Hitachi 44780 display IC. I've had it sitting around for a good while, so I decided to put it to good use. It is used to display current status of the music server...with the hopes that I will be able to figure out how to display zone status for each instance of Winamp. Currently I'm using LCDSmartie 5.4 to control what is to be displayed on the VFD.
