Glad you found my website helpful.
There is a page (
http://antiqueradio.org/parts.htm ) that lists popular sources for parts such as capacitors and tubes.
Once you have the schematic in hand, you should be able to identify the values of the capacitors. My recapping article also has a section on identifying values.
If the speaker cone does not have big pieces missing, you may be able to repair it yourself. Tea bag paper and fabric glue (or any flexible glue) provide an easy way to patch a tear or small hole. There is also a special speaker repair glue called "service cement," but I wouldn't buy that just to fix one speaker.
The dial face may be difficult/impossible to find unless you locate a junker with a good one. However, it might be worth contacting
http://www.radiodaze.com/ , which does make repro dials.
Most tuners can be restrung using braided fishing line from a sporting goods store. Be sure to get braided line, not the slippery monofilament kind.
Have fun!
