He was using it with "only 5 watts input" or words to that effect. Surely that would have driven the thing to full output? And on FM it would have given the amp a caning. Mabe just an internal fus, but I don't know if this model has such a refinement. Maybe risk it for a biscuit, but not much more.nondisclosed_email@example.com (Hot Fusion)Sun, 24 Oct 2010 10:02:05 +0000 Re: KL 500 RM CB LINEAR AMP (FAULTY)https://bfreebandingtalktheplanet.runboard.com/p15401,from=rss#post15401https://bfreebandingtalktheplanet.runboard.com/p15401,from=rss#post15401As long as its not the power transistors at fault, the rest is a easy repair.
