HP8553B mixer diodes

[Gary Schafer]

I have an HP 8553B RF section for the 141T spectrum analyzer with bad
first mixer diodes I think.



The old HP part number is 08553-6002 CR3, CR4, CR5, CR6.

I found a place that says the replacement is HP 10514-8454. This is a
matched quad set of diodes.



Does anyone know what a generic diode part would be for this?



Thanks
