I now pronounce this "Project complete"!
This was my first full restoration of any radio, and the 1st I have worked on that was this old. This would have been much more difficult (maybe impossible) without the help and support of the members of this web site and information in here. With the internet, parts availability has become easier as well as info.
Here are a few tips on this experiance:
1. Tube shield - PUT IT ON when testing this radio!
2. Open RF coil - had to rewind
3. Bad RF tube - checked perfect on tester, would start strong but lose emission after a few minutes under load, lowering volume
4. Volume control, I had to replace this, found used but good part, cleaned up with Deoxit
5. Big voltage divider resistor, bad 70 ohm to ground section. This was intermittent. Took months to find this one!
6. Repaired scratchy speaker by removing cone and cleaning.
7. When aligning, follow the instructions exactally!
8. Yes, full recap of all exc micas
9. Full set of NOS tubes
10. I lubed up the shaft on the tuner where it sits in the housing. This helped the slipping tuning shaft problem since the rotor turns easier.
A few comments:
Blessed are the ones that can simply recap a radio and have it work perfectly. Many were put up because of other problems, and this can be simple to major to repair. I feel for anyone who ends up with an intermittent or something difficult to find, esp if this is your first restoration, even more if your inexperianced with little to no test equipment. However, with the help of those in this web site, you can do it!
Here are a couple shots of the finished project:
Thanks For all the help and advice with this project!
