38-116 Restoration
#13

I think the chassis is about finished.  I printed some new station tabs but need to work on the color a bit to make it match the dial.  I'm working on the back lighting for the AutoTune dial.  I have a PC board being made that will allow 16 LED's in a circle behind the dial.  the LED's will shine through the dial and light the station identifier tabs in the Auto Tune dial instead of the reflecting ring that the designers used, which is ineffective.  It will use power from the switched 6.3v lighting that turns on when the Magnetic Tuning is on (for Auto Tune use.)  I hope it works out.  I was not impressed with the lighting on the 37-116 and the 38-116 is even worse.  I'll update when that is completed.

All tube shields have been tin plated and are shiny much like the original.  It adds a nice touch.

While I wait for the lighting circuit boards to get here, I'll rub out the cabinet and get it ready for the chassis.  The PC boards are coming from China so it will be a bit.

The radio has been working fantastic and I look forward to getting it in its cabinet. 

I rebuilt the coupling between the tuning mechanism and the tuning capacitor using rubber washers from the local hardware store. It works but there is too much flexibility. There are no fibers in the washers so they stretch a bit when tuning. This causes very slight tuning problems when I tune back and forth to zero in a station. I have to find a 1/8" think belting material that has a fiber layer that allows flexing but not stretching.
