I cannot help on the YIG device, but I do seek help on fixing the
horizontal deflection failure on mine. I have a full manual, but am
finding it tricky to drill down on the precise area.
Has anyone attempted repair of said YIG Ocsillator sealed assembly ("A6")?
in the HP 8558B Spectrum Analyser? If so, were you successful?

My copy is putting out -32dbm (spec is +15dbm); otherwise seems fine: sweeps
OK, freq is right on, etc.

I suspect the 3 transistor amplifier inside the sealed assy.

Any suggestions?
