This is my attempt to restore a G500, not museum quality but a daily radio that I can take everywhere, and not worry about it being beat up.

It's my first attempt to build a radio, using several schematics, reading the resistors, capacitors, using another G500 chassis as a blueprint for parts location, and for missing parts. 

If it blows up, so be it, its a learning curve and I'm learning. The resistors, capacitors are like greek writing, and the new parts codes is different so that's a handicap. All in all, it's learning, the sourced chassis was $20.00, the radio was $45.00, and new parts. So it's not a deal breaker, just labor intensive.




Before restoring the case:



As you can see, it looks like shit. The knobs and the buttons came with the radio.



The antenna is broken, I've lost a single push button somewhere, antenna is easy to locate, the button maybe a bit more difficult to locate, I will keep looking in my shop.

I sourced a antenna for the radio, it needs repair, and I have the parts.








The case was damaged, joints were loose, a hole was cut in the side.

After restoring the case:



As you can see I put it back together exactly like the G500, everything was re-glued, since all of the joints were dry with no holding power, broken wood was repaired, holes were covered up.


As you can see I chose to put in the extra tube holder on the back door from the H500.


Rebuilding the chassis:

The chassis has no rust anywhere, it has everything I need, the tower has been rebuilt.


The Celenium Rectifier is upgraded to a silicon diode.

The electrical cord has been replaced, modified to the 1950's.



The capacitors that are a hazard are replaced, the capacitors that are ceramic are left in place. 




The resistors are replaced.











The tower has been disassembled, rebuilt, some capacitors are replaced, all resistors, are replaced.











Tubes:

I was fortunate that I tested the tubes out and several of them tested as good on my old, old, chingaderas tester from the 1950's. 

Funny I have two testers, one is for the larger TV tubes and the other is for radio tubes, naturally I grabbed the one for the larger tubes and it's like WTF! I didn't realize that I had two tube testers.
