New here and not an electronics professional , so please bear with me if you don't mind. I came here, as it seems the best forum for a safe reliable project.
My project requires 3 voltages, filtered clean and 2amps each. 30,+15 & -15vdc. I have successfully built the 15's using 78 & 79's with a step down transformer. The transformer has 3 2ndaries. A 5vac, c-tap 16vac, and a 5 tap 19vac & 42vac.
I used a LM317 for the 30vdc. Currently I am current limited....haha and I don't know if I can use the one transformer for both regulated voltage boards I built and share a common ground. I'm thinking I cannot use just one secondary for both voltages properly. The transformer is 8-10amps.
Is there a better way?, devices, or suggestions. I have been searching for weeks, and have found two very similar psu's but the to did not have any more current than what the 78 & 79 & 317 provides.
I will post some pics of the modulation board and plans of what I have done so far. Thanks for all the great reading so far.
