Ed,
From a repair thread on EEVBlog the fellow replaced the 1826-0092 with a LM1558H to get his supply working.

I need to ID the HP part number 1826-0092, a dual opamp in TO-99. I think it may be a common, nothing special type like LM358 or 1458. It's an oldie, and I haven't been able to find it in any of the HP cross-reference lists I've found. It is in spot U17 on A22 of an HP8568A. The board layout can take a DIP too, so no big deal - I've got lots of parts in stock to choose from once I figure out what it's supposed to be. I suspect I have burned it out due to mis-connecting my home-made interface between the RF and the IF/display units - long story that I'll relate later.
Does anyone know what this is?
Ed
