Well my ADD side kicked in and I could keep my mitts off of that dirty rusty mess. See http://philcoradio.com/phorum/showthread.php?tid=12869 The plus to it is that it is pretty modular so I can work on small bit at a time. Thought the spkr panel would a simple start and I can use it with the HRO which is winding down.
Broke out the gojo and gave the wrinkle a good scrub. Cleaned up better than I expected with about 90 percent of the original paint entacked. That's the good part. I checked out the wiring to find that it needed some help. The pins that plug into the back of the receiver kinda loose and been spliced. I started the pull in apart and thought again that maybe I should give the spkr a try just for the heck of it. Well just for the heck I measured the primary resistance of the output transformer which mounts to that panel and I bet you can't guess what I found? OPEN!!! Did a little digging and found a suitable replacement. Meanwhile back at the ranch I removed the spkr from the panel to find several interesting things. The trim ring and grille cloth are copper painted black. I guess the Navy didn't fool around no rust there. The spkr has a removable magnet/pole. This is important as the cone movement is very rough. So next step is to remove the magnet give it a good cleaning to see if the free it up if so I can clean up the basket and paint it that way I won't get any bits of metal or rust back on the magnet/pole with it off.
