I've "inherited" an ESI-2841 network print server, but the AC adapter is missing. It's been about 15 years since I've been involved in electronics, but I opened up the unit and found that it uses an LT1076CQ-5 voltage regulator. The spec sheet for the LT1076 indicates that it has a minimum voltage input is around 8VDC and a maximum input voltage of around 40VDC, I'm concluding that I could use any old AC adapter that has a rectified DC output in the range of 9-12VDC (as long as I can find the correct plug).
Can anyone validate my thinking on this?
