Dennis, do you know the appropriate finish hole size in the PWB for each of these replacement sockets?

Hi Dave,
These are the ones I use with their corresponding DIgiKey and Mouser part numbers:
Mill-Max Part Numbers

0552-2-15-01-11-27-10-0 CONN PIN RCPT .015-.020 SOLDER

All three of these are still available from DigiKey.
Mouser Part Numbers

Is there a resource for the sockets that are soldered into the PCB boards in scopes with plug-in transistors, ICs, diodes, etc.?
Best wishes,
