IAIMH,
This is not the most friendly DIY amp to build. We were actually thinking of having these made by a robot and offered as a ready to run amp sans chassis/case. Great to see you are enthusiastic about it!

More progress - decoupling the input 3.5mm and volume pot for easier and more flexible mounting and assembly.

Getting yet closer...

I would like to get your feedback on interest in a pre-made 3D printed custom case for this new amp. Of course it won’t be cheap (free) like a mint tin. Probably $30 price range is my guess. Won’t know until we get number of interested people.

I would be interested in the new version of the PCA.

Great! I hope more people sign on with interest as well.

More progress from JPS64. The Altoids mint tin user interface is evolving. We are back to the through hole Switchcraft Jacks. There may be an all SMT I/O and volume pot mezzanine PCB.

I do find that it's easier to access the volume knob on my small portable amps, when the knob isn't between the input and output jacks.
