Going to get my station back up and running. I remember from years ago some trouble I was having with one of my tuners. Decided to open it today. Would like to get some input before I start doing repairs on it. Looks like I probably forgot to change the power setting while tuning up a rig and fried a few components. According to the schematic it's only the metering circuit. So worse case is I'll connect a swr/power meter inline and not worry about it. However, I'll attempt the repairs. Couple questions I have. That is a potentiometer right? Where do I find one? Should I replace the diodes? One looks black inside. Should I do a continuity test on the inductor? Close inspection shows it doesn't look too bad. How do I calibrate the pot after I replace it? Resistor is easy enough to find. Figure I better get some advice before I start.
