Hi Alex,Is J2 used to start up the circuit? I'm assuming it pulls up the input of the op amp when power is applied, in order to generate a voltage to allow J1 to begin regulating.Thanks in advance
Here is the latest schematics (for the unit running for 2 years now).
you know what they say about great minds
Here is the latest schematics (for the unit running for 2 years now). R1 is selected for the zero tempco point, R5 and R6 for 10V output.CheersAlex
Hi Alex, thanks for posting your schematic. I'm thinking of building one up and I have a question. R3 on the output is marked "k12" I'm assuming this is a typo and it should be 1k2? Thanks!
