audioguru Posted July 21, 2006 Report Share Posted July 21, 2006 This topic is about modifying the project for 5A of current.The "Projects Q/A" forum has the topic about modifying this 3A project to work well and reliably. I posted a recommended parts list there many times.The supply voltage rating of an ordinary 741 opamp is 36V absolute max and is the same for the TL081 opamps in the original project. This project with a 30VAC transformer and low load current has a supply voltage for its opamps of 50VDC. That is why I recommend OPA445AP high voltage opamps.
