Concertone ZX 75
About a year ago there was some discussion concerning a replacement for the Concertone ZX 75 used in the Surveyor SP 240. I think the replacement was a Jensen unit. The ZX 75 in my trailer has stopped working, and I would appreciate it if someone could let me know if there is a satisfactory replacement. Concertone has a new unit to replace the ZX 75, but it cost $400, and based on the poor sound quality of the old unit, and the fact that it only lasted less than two years, I really don't want to go there.
