This video covers a complete repair of the famous PS 305 Power supply. Symptoms are the Power supply is in protection mode with short circuit indication. By analyzing signals and electrical scheme, I found the 4 op amps of LM324 broken, and also the current loop not working. By substituting the faulty components and trim the potentiometers I regain the use of the power supply.
