Experience the Boulder house sound at real world price.
This amplifier was recently serviced at the factory here in Boulder, Colorado. New capacitors were installed (main board and output boards) along with updates bringing it up to current factory specs. Performs as new and sounding positively sublime.
Selectable between stereo and mono via back panel switch so you can upgrade to mono amps in the future. Stereo RCA inputs have been added allowing more system flexibility.
Some minor scuffs / scrapes as shown in the photos. Note: one minor scuff on the left side of the faceplate - only visible up close and in certain lighting. Second photo included for comparison, which looks worse than in person.
