    0-30 Vdc Stabilized Power Supply

    Audioguru, I just cannot get suggested OPs. What about old, good OP07? It's 44V amp...everything seems to be OK - the only parameter which is not too much impressive is slew rate. Advise please. Thank you.

    0-30 Vdc Stabilized Power Supply

    It turned out that D7 0,4W is OK. Previously, I ran simulation using different voltage source - skipped rectifier and C2 and put there DC sources. No issue. I am going to build 5A version, using 3 BD249 (no wires to heatsink). When I finish PCB design and put everything together, I'll report...

    0-30 Vdc Stabilized Power Supply

    Hello from Poland! 1.I found that OPA37 or OPA27 may be also used (OPA37 is slightly faster) - not tested. The only thing making me a bit sceptical is whether limitation concerning differential input voltage might be an obstacle. Audioguru, look at it please (just in case) as those two are far...
