Help locating wire-to-board connectors

[organics1]

Can't find the type of wire-to-board connectors I'm looking for and think the reason is I'm not using the proper terminology. I've found many different types that will work, but not these (circled in red in image).
I'm Building Rod Elliott's P101 solid state amplifier.
Any help would be appreciated.

Thanx

If they are 0.1" spacing then look up MTA-100 series at Digi-Key (or elsewhere) and filter for through-hole

There are many manufacturers of these types...also look for IDC type parts.

Thanks DUG.
Yes, they are 0.1" spacing.

Obviously, I'm new at this and discovering that the language differs and is diverse. But great fun.
It also pays to be patient and turn over as many rocks as possible in the search for the right stuff at the right price.

They are also sometimes called headers or pin headers and they can be locking or non-locking.
