Production changes: 16B
#15

Well.. there's good news and not so good news.

The good news is that I've managed to repair the shadow meter, as well as the tuning mechanism. The shadow meter problem was twofold: the vane inside was bent so that the beam couldn't display properly. And, the second was organic in nature... there was an industrious spider's egg sac in behind the vane, keeping it from moving. I removed that, and it instantly began complying. So, that's great.

Now, the not so good news.. not only can I still not get the two top bands to work on the low end, I've also lost linearity on the broadcast band. I attribute this to a possible faux pas on my part. Having tried everything else (new tube, replaced resistors and caps in and around the LO), and knowing that some Philco sets have been known to have coil problems, I removed the LO coil and gently heated it to melt the wax coating, and brushed it off, thus hoping to clear any moisture that might have been trapped within.

Upon reassembly, the upper bands had really not changed, but now I can't get anything like tracking on band 1. If I align it per the manual, the low end is sort of close, but by the time I get to the middle, 1242 appears around 1340 and 1440 is off the band. Retuning to get 1440 where it should be, 603 is now near 550, 973 is at 890 and 1242 is at 1090 or so.

Soo... I fear that I have damaged the coil, and it may have been possibly damaged before, and I made it worse.

Suggestions???
