Grunow model 580 only tracking on half of tuning cap
#5

That's what I'm going to try next is re-doing the alignment once I have the dial reassembled. The string was broken and so I had to take the whole face and gear mechanism off to get to it to restring. Once I have that on, and the face on and the dial pointers I can do a more accurate alignment and see if the trimmer isn't just turned in (or out) several turns too many. I had the tuner off to replace the grommets underneath and that could have messed up the alignment because I had to unsolder the wires from it. Yes I caught the "M" for 1000 ohms instead of the more common "K". Luckily all of the resistors I replaced still had vibrant colors so I could double verify from the schematic verses what the actual resistor code read. You're right though, years back when I first discovered that it was confusing to me as well! Will keep you posted once I get the dial restrung....next to coil rewinding my least favorite part of radio restoring!
