I am looking for the following items (perhaps some of you know of a source 
for these items or detailed instructions of how to construct the cables) --

	1. Tektronix 7L13 Spectrum analyzer plug in MANUAL
	2. Tek 7000 series EXTENDER CABLES for plug in repair & calibration
	3.  HP-141T Tracking Generator & Preselector CABLES
	4.  HP-141T IF & RF section calibration EXTENDER CABLE

All comments appreciated --
