Correct tool to adjust Pioneer SX-838 VCO? I need to adjust the VCO, the bottom coil that adjusts "Center" tuning so that Center is in fact centered when the signal strength is peaked. I have the correct tool for the top adjustment (5/64 hex) but can't see what the bottom is. Is it a smaller hex or a tiny flat blade? The service manual is no help when it comes to tools, although it's very good about adjustment instructions.

It is a hex tool with a long thin shaft; you need to push the hex portion through to the bottom slug.

Thanks, I'll need to see if I have one. Otherwise, I'll have to order one.
