I've just acquired a number of ALC lasers including an ALC68 with the ALC PSU; apparently the PSU had a meltdown, so it's been modified to run with an external choke, presumably as an AC current limiting device. I would like to try and rebuild the PSU as it was, although I have to admit to not yet opening it up to see if anything's been removed. If someone can point me in the direction of the schematics for the PSU, I would greatly appreciate it.
The alternative would be to buy a Meditec EIL-4000, as there are a couple of those for sale not too far from me at the moment, but they're not particularly cheap, so I would prefer to attempt a repair on the ALC PSU.
