Is there a secret to getting replacement bulbs to work? Some of the old bulbs were burnt out but even after replacing the new bulbs don’t want to work.

If you have some working, and some not,
I would suspect the grounding. Either in the
socket, or where they connect.

I took the cluster out of my '68 and got it up on the workbench, then went about fixing
any evident flaws in the board. After that, all new bulbs went in and were bench-tested
right then by use of a battery and probes.
Once I got it all working on the bench, only then did it go back in the car.
The pins on the main wiring harness connector are of primary concern, though - they come
loose often and are a bugger to repair without damaging other surrounding stuff.

Could actually be damaged printed circuit board

If you are using LED bulbs, they only work one way. If they don't light up, you need to turn them 180 degrees and re-install them.

They are just standard bulbs
