I can really recommend you to build your own supply for an ALC-60 head. It is not a big deal, if you have some electronic skills. If you are interested, you could take a look at my page (unfortunately it is written only in german so far). I've made a power supply for my ALC-60X heads and the bigger Melles Griot 643 Argon-Krypton-Laser.
If you've got any questions, please don't hesitate to contact me :yh:
My better ALC-60X head has 9 lines at a current of 8.5A (that's the one on my avatar). That is the maximum for ALC-60 heads. The other one shows just 7 lines.
