Hi everyone. I have an Astec AA11040B power supply on an Apple IIe. When I turn off the power supply, the +12v and +5v lines can take over a minute to drop to zero volts. (However, the -12v and -5v lines drop to 0v almost immediately after the supply is turned off.) The result is that I will turn off the computer, wait a 5-10 seconds to turn it back on and the previous session will still be on the screen. Just with a lot of garbled characters and nothing will really work... I often have to wait 2-3 mins before I can restart properly again.
I opened up the supply and replaced the RIFA cap because it was bulging, but it didn't fix the issue. I wanted to check if anyone has seen this or has any advice on where to focus before I jump in and start de-soldering caps.
