OR give me the circuit ,so that i can verify it... The power supply is very close to what's inside the Apple II, so find the schematic (it was in the Apple II manuals) and you have a good start. Of course, this is assuming the power supply is the problem. SOmething further on could be at fault, straining the power supply and blowing the fuse. Michael |
