Tektronix · Oscilloscope · c.1979 on
There was never a 465A. Tektronix went from the 465 straight to the 465B, which TekWiki describes as the same base specs with improved performance. Its manual was first printed in March 1979 (TekWiki dates the launch to 1980). It's a two-channel, 100 MHz portable with A and B sweeps and 5 mV to 5 V per division, showing four traces, CH 1, CH 2, their sum and a view of the external trigger. The easy difference on paper is the fastest sweep, 2 ns/div with the ×10 magnifier against the 465's 5 ns/div. There's no on-screen readout. The numbers you see in some photos come from the optional DM44 on top, a 3½-digit LED multimeter that also measures the time between two points on the trace and shows it as frequency. A 465B with a working DM44 is the one to hunt.
Options and accessories
Check the listing photos and the rear panel against this list, and ask the seller about anything you can’t see. A missing option or probe should come off the price.
It shares the 465 family's tantalum capacitors, which are known to short and kill the display or shut the scope down. TekWiki's repair notes also list one transistor type known to fail in the 465B, plus HV multiplier failures across the family.
New to used bench gear? How to check used test equipment covers self-tests, fuses, the voltage selector and shipping, and what “calibrated” means in a listing.
Buying guide
We'd buy cartridge_man07's plain 465B at $171 delivered with free shipping, well under the $220–370 band. There are at least 15 for sale, most complete ones ask $220–370 delivered, and shipping makes up $140–180 of that on five of these eight. None is titled with the DM44 or probes and few are titled working, so ask for the calibrator square wave on both channels after an hour's warm-up, and check the 115/230 V selector and fuse on the one shipping from Egypt. The $153 untested one with manuals is a project, and skip the two zero-feedback sellers asking $521 and $568 delivered.
$170.99delivered
The lowest delivered 465B not titled untested, at $171 with free shipping. The title makes no test claim, so ask for a photo of a trace on both channels before you buy.
Tektronix 465B Analog Oscilloscope
$170.99delivered
About $120 under the $290 median, which leaves room for a pair of 10x probes, since no 465B here is titled with them. Ask how it'll be packed, because knobs and CRTs break in a single box.
Tektronix 465B Analog Oscilloscope
$152.85est. delivered
Titled untested and READ, with manuals, at $153 delivered. Treat it as broken until it shows a trace, so it's for someone who can repair a 465B.
