March 25.
By now I have about half of the tuner chassis recapped (the right side and a couple on the left).

I am also replacing all of the old carbon resistors. Overkill? Maybe. But knowing how old carbon composition resistors increase in value over time, I know the radio will be happier (and perform better) with all new metalized film resistors as well as new capacitors.
Again, no restuffing of caps - you can see on the left side of the chassis that there are no original caps left to restuff.
One of the old resistors was the Micamold type, part (69), 500 ohms.
Having no 1 watt 500 ohm resistors on hand, I improvised by placing two 1000 ohm, 1 watt resistors in parallel to end up with a 500 ohm, 2 watt resistor.

Works for me...
You can see how burnt and bubbled the original Micamold resistor was in the photo above.
