Hello All, I picked up an old AMT Autoscale that has no power supply with a press purchase. I've done a google search and have found answers for just about every conceivable power supply one could have as apparently Lyman changed it a bit when they purchased the right to it. This unit uses an old school style 1/8 stereo plug. I used a universal Radioshack power supply at 9 and 12v. The optical sensors light up, but the motors only turn a little and I don't want to do any damage to it so if someone has one of these and can let me know the particulars that would be great. Attached are some pics of the internals.
