Ok. So I have decided to try a project from AAC. The project is a Battery operated 1 amp current source posted by someonesdad in 2011. The info is in Completed Projects under Power Supplies. Now some of the components are either obsolete or not available in my country (South Africa). So I have the following questions: Can I replace the Max872 with a LM336Z-2.5? Can I replace the Max480 with a TL071CP? Type "C' cells are very difficult to find in SA, can I use a AA cell instead? The 0.2 Ohm resistor does not show a Watt rating neither does does the poster talk about it in his PDF. Can I use a 0.22 3W Silicone Wirewound for that? Thanks.
