Peter:
The guitar originally came with an Alembic power supply, the infamous blue box. Alembic stopped making them years ago and switched to a rack mount power supply, though they have just announced that they will again be making a run of the old style power supply. I don't doubt that the DIY works, though I have no way of knowing if the specs are the same as the original. Either way it's still not the original, so to the extent that I value this instrument as a collector, any change from original, as in drilled holes, repairs, and non-original power supply devalues it some in my own eyes. Admittedly the DIY power supply probably has little if any effect on value on the general market. The broken headstock and holes surely have more impact on value. Nevertheless, I am interested in this guitar and will likely enter the fray before all is said and done.
