Printed on the side of an 8 pin round metal case:
- Something that looks a lot like a National Semiconductor logo
- S:/H246-1826-0678

There are three of those on a power supply board from an old HP 3325A
synthesizer.

If someone has the datasheet or the pinout of this component and would
like to share it with me that would be greatly appreciated.

Also, anyone knows where to get a service or user manual for this HP
synthesizer?

Thanks,
Jenalee K.

You can download the service manual from Agilent:
http://www.home.agilent.com/agilent/facet.jspx?t=80101.k.3&cc=US&lc=eng&sm=g&no=25

The devices you mention are LM358H op-amps. See reference designations
A2U2, A2U3 and A2 U4 on page 124; and power supply board A2 schematic on
page 393.
