The main reason behind this is because i was worried about having the amplifier power supply coming over a cable, If one rail was to become disconnected or short it is possible all the amplifiers could blow, or at least all stop working at the same time.
This way, if there is a bad connection it is between a speaker output and a "speaker" (the string drivers are not much different from a speaker, basically a coil.) and the amplifier chips have short circuit and open circuit protection. even if one blows, it is relatively easy to change a single one out rather than the whole lot of them.
The disadvantage is that there are now 3 cables, the speakon, the roland GK, and MIDI. before it was just MIDI and 2 nice light ADAT optical cables.also i dont think the speakon is really very optimal for real stage use because the guitar will be firmly attached to the controller box. However I doubt that *I* would ever be going on stage with this contraption!.
An advantage, though is that i do not have to cram so much stuff in the guitar, and the guitar will be lighter.
In other news, 3 of the amplifiers are completed and tested. (and the amplifier power supply) they worked right away, the boards are quite easy to build up.
For the power supply i found a nice torroidal transformer inside some horrible slimline "home theater in a box" which someone had thrown out.It has 13-0-13 secondaries which after rectification give +-17.5 volts.which is very nice for these amplifiers. they can produce 15 watts from that.
Also i found a server case which is almost suitable. It is aluminum, but way too long, i will have to do some modifications. mainly to make the hole on the correct place for the riser card, shorten the case to about half its length, and make a front panel..
How do i put this in laymans terms now? well i cant :D sorry hack a day internet sensation guidelines!
