Описание: The PCB have arrived from pcbway.com so I built the prototype of the 140W Multiload. It seemed to work OK until I got up to about 50W and then one of the transistors went short. Why did this happen? Well it turns out it was due to a simple design error. Find out why in this video and hopefully learn something like i did
