Most caps available except I couldnt locate the big cap at the correct height or diameter on mouser / digikey

Thats a rifa / safety cap. Thats what they do when old. They blow and smell bad. Never experienced one personally thank god🙂 will have to check the value..


Macdat.net might have info for rifa. Will see if i can find any info as well

I think I used two smaller capacitors back to back to replace this when I've done Duo supplies before. I'll see if I can find that part number
