The "Mac Daddy" of analog oscilloscopes!
Let's start with two important facts: 1: Tektronix - world renowned maker of oscilloscopes for decades. They still make really great digital scopes too but these old analog scopes were built to last! The 465 model has been around since the 1970's and you still see plenty of them in use today. Which brings us to fact #2 - Model 465! This was the first truly portable scope and it was built to take the rigors of traveling techs. And Tektronix made a boat load of them so you can still find plenty of them in working order and some that aren't that are useful for parts. Which brings us to another important point. The new digital scopes are great and they do a ton of stuff the old analog models can't do BUT.... because everything today is manufactured using proprietary semi-conductors and surface mount technology, when a digital scope goes south you are left with a very expensive boat anchor because they can't be repaired. The 465 is put together using common components that can still be found today with little trouble (the exception being the tunnel diodes). There are no proprietary chips or surface mounted components. Translation: a guy with a soldering iron and small tools can still repair them! In fact, there are a number of shops around the country that specialize in repair and calibration of old Tektronix scopes. And all of the tech manual to maintain them can be found online for free. Having said all of that, if you're looking for a used analog scope it's always a good idea to only buy one that's showing wave forms from a function generator. Never assume it's working unless you can see it working. At very least probes for both channels should be connected to the probe compensation node on the front of the scope. That should at least show you a couple of square waves. I was really pleased when I connected my scope to my function generator and was not only looking at valid wave forms but they were actually reasonably calibrated as well! That's a bonus because you'll probably have to perform some calibration otherwise. But once calibrated, the 465 is an amazing tool. Now if your dealing with really high speed digital circuits, you'll need a digital scope. I'm working on audio stuff. Specifically guitar amplifiers, effect pedals and processors and analog synthesizers. This is a 2 channel 100 Mhz scope so it's well within the parameters of the audible frequency range. Expect to pay at least $300 for a used one shown in working condition but considering they used to cost around $1800 in 1975 money, it's a bargain! And when dealing with audio, sometimes a digital scope can be a little to accurate if you don't compensate it correctly. You can find yourself chasing ghost that won't even show up on an old analog scope. And it's good that they don't because you can't hear them anyway. Overall, I consider the Tektronix 465 to still be one of the most reliable and useful tools you can own for your lab especially if you're a hobbiest or DIYer. You can still get parts, they can still be repaired on the bench and there is a ton of documentation available on the internet for the asking. And on a personal note, I'm not wild about all the menus and soft keys on digital scopes. Call me old school but I still like a bunch of knobs, switches and buttons! The Tektronix 465 feels like an old friend. I wouldn't trade it for anything.Verified purchase: YesCondition: Pre-owned

What did I expect for 35 year old equipment
It did power on and display traces, but it had a very hard time triggering and the waveform was not accurate. It had trouble even when connected to a signal generator with 'perfect' wave forms of different types (square, triangle, sine) and frequencies. In the 80's - 90's as an electrical engineer I used one of these almost daily. Electronics is now a hobby and I was looking forward to adding a scope to my bench. I guess I was expecting too much from a 35 year old piece of equipment.Verified purchase: YesCondition: Pre-owned

A great scope for the money.
The TAS465 is something of an under-valued oscilloscope - they are relatively inexpensive today. Still, this is a feature-packed analog oscilloscope. It's microprocessor controlled, menu driven, with relatively intuitive controls. The measurement system measures volts, time and 1/time. The auto-setup feature is quick and makes measurements a snap. If you need an inexpensive scope for your bench, you really can't go wrong - just look for a scope without burned phosphor. Also, these scopes use a hybrid IC that can be difficult to find / replace, making them a bit un-economical to repair; but for the cost of these scopes on the used market, it's tough to find a better 100 MHz analog scope for the price.Verified purchase: YesCondition: Pre-owned

Tektronix 465, vintage 100Mhz analog dual trace 'scope, industry standard for many years
Very well packed and arrived in excellent condition. Works very well just as described. Minor paint scuffs but these were mentioned in the ad. I did rough checks of the calibration right after it arrived and it appears to be spot on.Verified purchase: YesCondition: Pre-owned

Best Tek Cord Wrap Feet
The replacement cord wrap feet are better than the original. I bought a set for my Tek 465b and they are fantastic. Not only are they well machine and look good, they are strong as hell and take a beating. You can not go wrong !! Thanks & 73, Dave K2DCGVerified purchase: YesCondition: New

Tektronix replacement cordwrap/feet
Vintage Tektronix Model 465/475 oscilloscopes purchased on E-Bay often have many faults, such as the rear mounted rubber feet quite often are missing, damaged or worn out from time and neglect. Original replacements are difficult to source and are of limited quality and expensive. Why not buy a set of new material replacements machined for a custom fit.Verified purchase: YesCondition: New

TEKTRONIX 465B is a Great Product.
The 465B is a great addition to any serious hobbyist's workbench. These things exude quality. There are some things that a Digital scope just cannot do. The 465B is a prime example of good Old American workmanship, the kind of craftsmanship that sent men to the moon. You just do not find this kind of quality in today's devices. One of the last truly "repairable" oscilloscopes. The 465B uses LED's for the panel indicators and this is important, since replacing the indicator lamps on the older 465 and 465M is a real beast of a job. I just love the look and feel of the entire instrument.Verified purchase: YesCondition: Pre-owned

Scope for a Hobby
The scope is exactly what I need as an electronics hobbiest. I was used to using a scope like this when I was working, but could never afford to buy one. Now, that I am retired the price was right for for me to buy one to continue with my hobby. Thanks Ebay.Verified purchase: Yes

Tektronix scope feet not on the market.
This was a great idea to build these feet yourself because they are no longer available anywhere on in the market or internet. It's about time someone took it on their own to do this. Job very well done.Verified purchase: YesCondition: New
