HP8553B mixer diodes
 

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

There is a Tek repair group on Yahoo.

The manual for the HP8553B is on bama.sbc.edu in pdf form.
The diodes are nothing special but are matched.
