What are these

[alrainbow]

The part tested ok and seems to a 15 volt reg 

mc 7915ctg

mc 7815ctg 

 

Bottom right is where the reg were 

Below the vishey 4700uf caps

They seem to be some sort of discrete voltage reg made to replace std. 78xx/79xx regs. Sparkos makes some, and I saw some on aliexpress, but nothing that looks exactly like these.

Ok thanks. At first I thought exploded lol

I removed them and replaced them. I tested them and they work fine
