What amp should I build?

[YourGuitarist]

I packed mine in a home-made box about 7x5x2 - zero noise in mine from any transformer coupling. I did add a choke in the power supply stage to minimize any hum issues.

Cool looking shields. Nice overall aesthetic.

I assumed the choke would emit a magnetic field. I see how it filters the electrical path in supply. Further thoughts?

How's the Hammond working for you?
