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?
