Bendix 0526E FIVE tube radio.  This radio includes a plug in style octal ballast tube.  The series filament string adds up to 71 volts.  The ballast takes up the difference of 120 - 71 = 49 volts.

Well, Kevin T send me an email pointing out this is a simple AA5 tube line up.  I appreciate that!  See the schematic here: http://www.nostalgiaair.org/PagesByModel/342/M0002342.pdf  Any semi familiar radio fan will immediately recognize this error.  Now all I have to do is figure out what radio this ballast  tube belongs to. Thanks Kevin!   Paul..

Initial test found two bad tubes. The 35Z5 has an open filament.  The 12SQ7 is dead (no amplification or diode rectification).  Once I replaced those tubes the chassis did receive stations while on the DBT.  If you are wondering how I can test an un-restored chassis please see my latest presentation on this page.

A refinish is in this cabinet's future.

This does not look like a Walnut finish.

Duct tape.  I will see about a new rear cover.

I would bet this radio was made on March 19, 1946.

The service documentation indicates pre 1951.

The wires to the lamp and audio transformer are cracked and missing insulation.

See the dial lamp?

Dim Bulb test the chassis.  Passed. 

IMG_6183.JPG (181856 bytes)

Some bad insulation...

IMG_6184.JPG (153056 bytes)

...But not a whole lot.  Just a few wires taken in stride.  

IMG_6189.JPG (169921 bytes)

Dirty.  Cleaned with Odorless Mineral spirits. 

IMG_6193.JPG (163497 bytes)

Dirty too.

IMG_6196.JPG (157199 bytes)

Cleaned. Trimmer cap mica is contaminated beyond cleaning.

Nice!

This back came in taped together with Duct tape.

If gluing and pressing fails then I will cut a new rear cover.

It failed...Ugly....

 

IMG_6262.JPG (147771 bytes)

A new fabricated back.  1/8" plywood is perfect for this job.

Tom "Finishing Touch" used appropriate stains on for the different wood tones.  He is an artist!

This cabinet turned out better than I expected!

More pictures to come once I resolve the rear cover issue.           
           

* I have a friend Tom that is doing most of my refinishing since late 2009. Wood finishing has been his profession and he is much faster than me. It takes Tom a fraction of the time to accomplish (strip, stain, color blend, repair, finish, etc) what takes me a week to do.
