I am inquiring as the the resale value of a 215sh cabinet with original electrovoice SRO drivers and a beta bass head. I believe they are of early 80"s vintage. The equipment is in very good condition. One of the potentiometer shafts is broken but still works and I have the knob. Other than one or two tiny tolex tears the condition is perfect and all works. I also have the footswitch for channel selection. Anyone out there that could inform me would be greatly appreciated, thanks from BABASSKA.
