Hey! I like your opamp pictures, really great :). Why didn’t you buy a steel or aluminium case for shielding?

I need to get them outside my country and they get expensive, I do have 5 little ones for portable use but at 20€ for case you get why I didn’t buy a big one. I could actually shield all the case with that aluminium tape but I’ll just shield the amplifier board & crossfeed boards.
🙂 Tks for the question!
