Re: TDS-420A power supply repair
Hi , I checked for that sort of thing last night . I removed several of the caps and found no tell-tale liquids on the pcb and having checked them for shorts , as I had no replacements I put them back for now . Them mains fuse had blown and when I looked at the psu there was a burned track which I have repaired . As I have no Variac I have not dared to try turning it on again without a load even in case the cause of the burned track only makes more damage ,toggle quoted messageShow quoted text

I know the TDS420 NON A that i just repaired the power supply on every single capacitor had failed. They mostly looked fine but when you removed them there were puddles of liquid underneath them.
