Help with NAC 72 board id needed

[Liquid]

Morning gents.

I've stumbled across two pairs of boards in bubble wrap. Can one of the enlightened let me know what they're for?

324/7
325/1

Thanks in advance.

324/7 are tape buffer boards

325 are the relay boards which connect the output on powering up.

Cheers Jo.

Without looking too much like a div (ooops, too late) could you explain what they actually do?

The tape buffer boards are unity gain:
