i popped a ELG-150-36A a while back with overheating it constantly.
decided that in the name of science
i would destroy it even further.
here is the link to the full res album: https://imgur.com/a/fVMnFP0
the pcb is made from cheap fiberglass. but all the components are the highest quality you can get, rubycon 105c caps and so on.
separation is basically perfect, input filtering is textbook-with-cherry-on-top. even put a shield on top of the brain-box,
i dont see how a HLG would be of higher quality. prehaps a nicer pcb or something. the only difference i can see between a HLG and ELG would be the casing. this is folded aluminium and a HLG has extruded aluminum. but i expect they are basically identical from the inside.
