- If you have the light one supply, there has been broblems with one resis-
- tor at least.
- I don`t remember value of ity anymore but it is located to primaryside
- of supply. it`s surely over 300 k Ohm and probably 1-2.5 W=(bigger
- than many other resistors). Also blown diode or bad condensator after
- transformer (secondary side ) have been caused same kind of problems.
- Anyvay i have seen at least 6 diffrent types of amiga (orginal) psu`s, so
- I can only hope that you have some help with this.
