Okay, first off, mods if this isn't appropriate, please move as needed. I figure WECO was the daddy of it all so this should count.
Anways... I just picked up a full Beach Master system, amps, speaker array and spares to keep it up and working. The problem is there is so little information out there I am taking this to multiple boards to see what input you may have. I have many pics if you need them. Please let me know what info you have?
