Help! Can anyone tell me exactly where the springs on the model 87 dial cables anchor?
I have the radio electronics rebuilt including re-capping and it works, but the dial cables
have me stumped.

Not sure if the 87 and 89 are similar in stringing, but I found this thread on Antique Radio Forums, hope it is helpful. There are a couple of pictures a little way down that may help. http://www.antiqueradios.com/forums/view...p?t=193224 . I have also used braided fishing line for a replacement for dial cord, just buy the thickness that looks close to what yours was at a good fishing tackle shop. Also, Radio Daze sells dial cord, although I'm not sure of its size as I have never bought any. Good luck to you.

The 77 and 89 are different than 87and the 95. It has two worm gears one at the front and one at the rear connected by the tuning shaft. At one end of each gear there is a peg. A loop at the end of each cord (there is two cords) slips over the peg. The cord is wound around the gear (would start with the rear gear) and then it is fitted over the dial drum thru the small hole and a spring anchors the cord to the inside of the drum. Same w/the front cord but it's would in the opposite direction. One cord pulls and the other pushes which in turn rotates the drum. GL they are a pita to replace. One tip is if you have a good cord measure it to get the correct length from loop to loop. I'm pretty sure there are the same length.
Hope this helps and have fun making up new bad words. [Image: http://philcoradio.com/phorum/images/smi...wisted.gif]

When I had to replace one of the cables on my 95, 2 or 3 years ago, I think I found some very small cable at my local bait and tackle store, but would not swear to that. I can’t remember, either, what I used for cable ferrules. As Terry said, though, it is a PIA, and requires lots of patience and a good vocabulary! (I sure found just how limited mine was!) One thing I found handy in the process, though, was the use of the small Vicegrip pliers to act as a 3rd and 4th hand. As Terry stated above, only one cable at a time “pulls” the dial drum at a time, depending on direction of the shaft turn, while the other just maintains tension on the drum, as it unwinds. They should both be taut at all times, with no slack in either cable, or it will all come unwound into a small rats nest.
Perhaps, braided nylon fishing line would work, but I was afraid that it would stretch, over time, requiring a complete do over. I didn’t want to go thru this again. Good luck, and have fun with it.

I'll mention in passing one 1st I did was back in the 70's and didn't have a source for metallic cable. I ended up using steel wire used for hanging pictures. It was fairly easy to work with and could solder loops on the ends. I don't remember the ga but would guess abt 18 or 16.

Double conversion is using two IF converters instead of one. This improves the image response.
