Edit: re-named as not apparently NRG!

I'm sure that first picture is a Pantek layout, not NRG. I've also read in the past that it's pretty awful too.

Yep, definitely not NRG at all.

...Isn't that the nasty thing with the two 2N3553's together? ?

PCB on the first picture is shitty RF wise. And i don't know what it is

I got given one almost 15 years ago and the person bought it many years before that, they're very old.

....I just removed parts from it and never used it, still got the old board here somewhere but with many parts missing. I have no idea where it is though, I just remember it has 2x 2N3553's running in parallel together as an output stage.
