Agilent PSA E444x series SA component level information

[alan.bain]

Does anyone know of a source of component level service inftormation for the HP PSA series Spectrum Analysers?

I have just repaired a PSU and suspect I have a fault in a LO - possibly the second, but the service manual only has a schematic of the backplane (which I admit was useful when fixing the PSU) but a little more information would be useful. I can find limited clip info on the ESA series but nothing on the PSA.
