Thanks much for the responses. I remember back in my performing days when these were around a grand. Funny, all the stuff I like is cheap now, Crowns and blackface ADATS. Stuck in the '80's.
I now remember that these amps have no speaker fuse protection. So, if I make cables from the amp out to a 1/4" female with fuse holder on the + (red), and plain wire on the black, I should be good to go. Advise welcome, I also remember blowing speakers in my youth as well. Going to use this to power drum monitors. 1 15" and a horn in each. Many thanks
