A little work today before lunch. Replacement of the two most inaccessible caps beneath the RF coils and bandswitch assembly is complete. I had to unscrew and move the side panel to get in there, so it took a little time.

One thing I wanted to pay attention to is observing the outside foil connection for the new caps. But how to determine this with the new caps that are not marked? Easy. Clip the cap across the input to a cheap guitar amp. Note which lead is connected to ground. Grab the cap without touching the leads. If the hum increases, the cap's outer foil is connected to the signal line, if it doesn't increase, ground is connected to the outer foil. Then I mark a band around the appropriate end of the cap to note the outer foil lead.

More caps after an afternoon walk.

I don't hold with furniture that talks.
