I appreciate your help here. My dad wants to start using his Sony D100 again, but cannot find the power supply. It says DC IN 9V. Can you recommend any power supply available on the internet?
Thanks in advance!
I'm 99% sure the Sony Discman D-100 (manufactured somewhere around 86/87) uses a 9V negative tip power supply common with models from the D-5/D-50 through the D-150, D-250, D-555, D-9, D-40, and D-350. A Sony AC-950W or AC-940A power supply will provide the proper voltage/power. Also, a lot of Panasonic phone power supplies (the bulky grey ones) provide the proper fitting plug and voltage. Just make sure you get one with at least 500mA max current (600mA is better) and a negative tip. If you want to make sure, check the picture on the back of the D-100. It should have a '+' with a line pointing to the outer ring and a '-' with a line pointing to the inner ring/dot. This indicates the center of the plug, the tip, is negative relative to the outer portion of the barrel plug.
I'm posting a picture of an AC-940A that I took from an eBay listing. Make sure the diagram looks like the one on the back of the D-100.
