Hi All,
I'm in a apple II repair month
I have this Astec AA11040C supply that had the usual smoked rifa X2 capacitor. Other than that, it's outputting about 5.5V on the +5V line and 13V on the +12V line. However, with a 7 ohm load on +5V, the rail goes to 5.0V. I'll check the ESR of all electrolytics, but I was curious to know what's the minimum load (if any) to start regulating correctly the +5V rail?
Is there a schematic of this power supply floating around?
Thanks in advance.
