WTB: HP/Agilent 1NB7-8458 input attenuator (500 MHz) for 5461x series scopes

[stefan_o]

Hi,
I'm looking for two 1NB7-8458 input attenuators, they were used in many HP/Agilent products back then, like the 5461x scope series. I do not need a specific housing, just the boards, like in this picture (not taken by me).

Preferable from somewhere within the European union to prevent import taxes.

Best regards,
Stefan
