Tubesville's Blackie Pagano has a thing for all things shiny and silver - the building's facade glistens like the chrome guts of the tube amps and hi-fi stereo equiptment that litter the space inside. Pagano is a rock 'n' roll nurse, and Tubesville is where he performs open amp surgery. His patients have included the amps of Lou Reed, Sheryl Crow, and Jon Spencer. Pagano averages a one-week turnaround, with a trauma unit for 24-hour rush service (at an extra charge).
