does someone can tell me what is a schottky diode please???? is there a schematic about the new circuit with udpates? because i’m bad and i don’t understand where i have to insert a jumper… ( the jumper is here to shorcut one of the diodes???right???)
does the last photo represent the first schematic or the second??? i’m not sure but there there ‘s a lot af componant into the box and the second schematic no…

Hi tazinnuedo – you can use a 1N34A germanium diode in place of the Schottky diode. Schottky diodes exist primarily because of very fast reverse recovery time – useful in switching power supplies and class D audio amplifiers. They tend to have a lower forward voltage than silicon diodes but the germanium 1N34A does better at the lower forward currents such as exist in the Raper circuit.
