The double row of push buttons are all lit and they dim when I push the dim control. Only the amber backlights are affected. Where can I buy the correct bulbs with the rubber grommet ?
Thanks for the replies !

Yeah....but did the display blubs both go out at the same time? If they did, then something else besides the bulbs themselves went out. A resistor or something. Or a solder joint went cold.
These display assemblies are not the easiest things to work on and you must exercise great care.
If you just go and change the bulbs and they still don't work you will be mad !!
I did have bad bulbs on a 2970 and I replaced them with orange LEDS. I stayed with orange as I liked the look but they could be changed to any color.
I forget what voltage the factory incandescent bulbs run on. May be 12volts. You can easily find that out by checking what voltage is on the bulbs leads with the radio turned on and with a DC volt meter. If there is NO voltage across the bulbs, then as mentioned before, the problem is somewhere else.
If bulbs are bad and you want to go back with incandescents, Radio Shack should have them or any electronics parts house like Mouser or Digikey or any decent CB repair shop should have a bin full of them.
I buy LEDs from eBay. You'll need appropriate resistors to go with them depending on the color you use. different color LEDs tend to operate on different forward voltages and therefore need a resistor matched to the their operating voltage.
Then you may have to have a qualified tech look at it.
Good luck
