    Guitar Aplifier

    Yes, I followed the instrucions, but I am afraid you're wrong about the transformer. The schematic I made is similar to original one, just that I used rectifier bridge and 48V transformer. If I understood you right, I used too high input voltage ??? Why I should reduce it to 24V?

    I don't have transformer with 3 contacts and I used 2 way one. Can anyone check, if schematic is correct? I have tryed circuit, but I didn't connect the speaker and one of the transistors died becouse of the too big current through it. I am now waiting for new trasistor to try my PCB.

    Power Supply 0-30V

    Hello, I have build this power supply long time ago, and it didn't work correct. U2 was overheating and output voltage of supply was just 25V. I have changed opamps with OPA455 and now works the same. I have checked every connection, every transistor and diode. Everything is correct. Can you...
