[Hallicrafters] Last call on some test equipment

[John Hensley]

Repairers of the antique & bodacious:


...last call on this test gear all of which need a good home.  The equipment works, has been used in the past, may need to have some controls or wafers cleaned.  Many a Heath & Hallicrafters have been brought back to respect using these:

Oscilloscopes:

AN/USM281 (Ruggidized version of the HP-180A, made for the US Navy).  Has standard 50mhz plug-ins, dual trace, needs to be used.  Good choice for DC through HF.

Tektronix 561B (manual on BAMA or email me for copy).  Has stock plugs-ins.  Good choice for a back up scope, good for DC through VLF and up to about 20 meters.  Needs to be used.

Capacitor/Resistor Comparator

Eico 950 (have two); commercially built by Eico, dusty but cabinets are like new.  Power up fine, magic eye has hardly any hours on it, bright & responsive.  These are very useful for reforming caps, building balanced line filters or making up caps to meet another caps value, etc. etc.

HP 3455A Lab Multimeter

5 - 6 DIgit resolution; lab quality unit,  can be used alone or rack mounted.  Unfortunately, it is locked up and not responding.  If you're a flip-flop analyst, this may be just for you.  Descriptions vary but here is a typical description:

The 3455A Digital Voltmeter is a microprocessor controlled, 5 1/2 or 6 1/2-digit voltmeter for bench or systems applications. The standard instrument measures DC volts (0.1 to 1000 V range with up to 1 µV sensitivity in five ranges), AC volts (1 to 1000 V range in four ranges) (ACV or FAST ACV), and resistance (2 W or 4 W: 0.1 kohm to 10 Mohms in six ranges). HP-IB controllability is standard. The standard True RMS converter gives AC measurements from 30Hz to 1MHz and the math function provide computational capability. The scale mode allows the user to offset, take ratios, or scale readings to give readouts in physical units. The auto-cal feature checks the DC volts and ohms operating circuits against internal references and corrects them digitally.


Will trade for what have you.  Need a good VHF duo-bander, hand held or mobile.  Cash offers considered.

Thanks,

John
