This Gibson BR-6 Model Tube Amplifier was made around 1947 in Kalamazoo, Michigan. This was one of Gibson's less expensive post-war amps. It has two inputs but only a single volume control. The bottom mounted chassis has two 6v6 power tubes put out 8 to 10 watts. It has a single 10" field-coil speaker . The BR-6 definitely has a no-frills feel but is still a well-made and good-sounding amp, intended for students or semi-pro musicians. It’s original brown fabric covering is in good shape but it does have a few scuffs, scrapes and scratches. The paint on the amp’s chassis does show a fair amount of corrosion.
