odd connector type cannot be found

Hello,

I’m repairing a Pioneer AVR. The circuit boards use unusual connector configurations.

The connectors have odd numbers of pins in two rows. The rows are staggered, brick style.

I have tried searching the web with Google, but without success in finding such connectors.

The connectors are board-to-board and are pin/socket design.

Any ideas on what these are called, who makes them or where I can find them?

Thank you,

Jim J.
