Hi Sherlok!

I like the idea of a second card. I think there is room, but I need to double check. I was considering using fish paper for that purpose, but a card seems like a more robust solution that will also say more loudly to other techs who may work inside the amp: "DON'T REMOVE ME!"

I can see where you're coming from with respect to aesthetics. Personally I think I'm fine with the exposed threads, we'll see how things wear on me. I'm figuring on using a regular nut and washer to hold the top card down against the bottom card against the nylocks beneath that. Given I'm not using nylock screws/standoffs for the other cards I assume this is fine, but should I actually use locking nuts (or maybe threadlock?) to secure the top circuit card?

Thanks!
