What are the required punch sizes for 4 pin, 8 pin and 9 pin sockets? Also, any recommended sources. All I seem to find are for electrical conduit work.
You can take a look for “radio chassis punch“ on eBay. I prefer a vintage Greenlee brand which are great quality. Some unused even at 50yrs old or so. I have had good luck with the “make an offer” listings
