My Crack has a couple alterations, including: teflon tube sockets, locking Neutrick 1/4" jack, Kimber Cable RCAs, Kimber TCSS wiring, metal toggle on/off switch, brass top plate, DIY RCA, headphone, and power cables, and a Speedball. I used an Early American Minwax stain to contrast with the brass, and I just polished the transformer bell. I love this thing, it sounds amazing!
