ASK SILICON CHIP

摘要

Looking at the power supply PC board for the Studio Series Preamplifier(SILICON CHIP,October 2005),why do the tracks from REG1®2 go to the external terminals first and then back to D5 and D7?Why don't D5 and D7 connect directly to REGl®2,as shown in Fig.10 on page 31?(J.E.,Silverwater,NSW).
