Okay Kenwood gurus, I need your help! I just don’t understand where to put my leads based on the instructions provided. What am I missing? If I am measuring current don’t I need to unplug something and measure the two connections points that were unplugged? I just bought this for $150 and was told everything works... well... not quite. I get protection coming on every so often and I turn it down and it comes back usually after a few seconds. For some reason I cannot have A and B channels on at the same time? Drops all dc offset to flat 0. It looks like it needs some caps replaced (naturally) and I intend to start down that path for the power and amp sections very soon. However I want to see if I can solve the protection issue first? First thought was bias. It’s weird because I can have the volume up pretty good and hold steady with no issues for 20-30 minutes. Sometimes low power will trigger as soon as I turn it up a little. Anything else I should look at specially or should I get my money back and run? The guy said he would give me my money back but it is a nice unit and it sounds great! Hearing this unit I realized that on my SX-650 the lows lack, the mids are absent, and highs are a little too bright. I love it I am just don’t want to go too far down a rabbit hole since quads are not the easiest to service and not the cheapest either. I am nervous to look up the cost of the main caps since they are monsters which of course gives me that smooth bass sound Included a couple noodz and shots of the SM in hopes it makes it easier to dumb it down for me! Thanks in advance!
