It looks like most in the series use 8 volt 300 milliamp lamps, see link:
I bought all the new lamps for my TX-8500 at Radio Shack. The details and part numbers are on the page Viridian referenced above.
Not sure about the meters since mine were fine, but the stereo light was out and required soldering. The dial lamps are bayonet and really easy to replace. Good luck!
