In my 0-50V 2A Variable DC bench power supply (Refresh) LAB, Someone commented that the current limiting part of the circuit was incorrect. This circuit had been working faultlessly for forty-years so I trusted it. However, I thought that I should take these comments seriously and this project is an open invitation to Elektor readers to add there own comments to the investigation.


This is a suggested circuit revision for the current control circuit of the Variable 0-50 Volt 2 Amp dc bench supply (Refresh). as compared to the Elektor original.
Please give your comments regarding the two designs. 
This exercise is a theoretical investigation in to a reportedly broken circuit! previously published in Elektor 1980 in conjunction with the Texas Instruments LM10 Design Notes.
