Hi. I’m new to this forum. I’ve had a couple of PS Audio components inn the past but just recently came across an SR-1 Source preamp. I was wondering if it would be possible to get a schematic in this forum? I’m having a power supply conundrum that I need to address. Thanks for any help! ---

Hello, I dont know of anybody having schematics, they are rare, so rare in fact that I need parts for mine and would be interested in yours if you are so inclined. If not, I can send you photos of what you need in case that helps. Thank you. ---

Sweet, strange yours has the power supply inside. I thunk these may have been a kit. Did my ohitos help you figure out your issue? ---

Oh no, I thought you had an issue with yours and were looking for parts or something. I moved the pwr supply inside the chassis. Since it’s in a Faraday cage, there is no reason for it to be outboard. All it is is a simple step-down transformer. Nothing else. I also added a line filter to it. ---
