Threshold SL10 PREAMPLIFIER No Power Supply. The unit works but still listing it as parts need repairs. since there is no power supply to test it with. I moved on to other preamplifiers and must somehow threw away the power supply while moving. I searched and searched but pretty sure is totally lost and gone. There is one on sale on Ebay . The condition is very good for its age. I post as much pictures as I can to help you decide on the condition of the preamp.
